When detection of an abnormality in a fuel vapor treating system is executed, a vapor zone including a fuel tank and a canister is sealed. The sealed vapor zone is pressurized. Whether fuel vapor is leaking from the vapor zone is determined based on the pressure in the sealed vapor zone. A canister
When detection of an abnormality in a fuel vapor treating system is executed, a vapor zone including a fuel tank and a canister is sealed. The sealed vapor zone is pressurized. Whether fuel vapor is leaking from the vapor zone is determined based on the pressure in the sealed vapor zone. A canister valve selectively connects a canister with and disconnects the canister from the atmosphere. During the abnormality detecting procedure, an electronic control unit (ECU) shuts the canister valve. After the abnormality detecting procedure is ended, the ECU sends a control signal having a predetermined frequency to the canister valve, thereby gradually increasing the opening size of the canister valve. Accordingly, the pressure in the vapor zone is gradually lowered to the atmospheric pressure. This prevents fuel vapor adsorbed by the canister from being released to the atmosphere.

UB>n-1up to the (n-1)th polygon according to the accumulated transparency value Xn-1of the (n-1) number of polygons positioned at the front for rendering processing. This rendering processing is executed for all polygons, and the final image data Dnis used as image data for display. In accordance with the above image processing, translucent polygons can be sequentially processed from the front, so rendering processing of important polygons positioned at the front in a display screen is not omitted, even if the time between frames is short. Therefore images with smooth movement can be reproduced without stopping movement of important characters comprised of polygons. The above image processing can be applied to general blending processing as well. rations of the executing process while still allowing the user to see the application window; and (d) moving said transparent window behind said application window in response to a timer interruption that occurs after a predetermined time elapses since said transparent window has been moved in front of said application window in said step (c), thereby allowing the user to apply input, via the application window, to said process. 7. A method according to claim 6, wherein the step of moving said transparent window in front of said application window includes the step of: responding to a given error input from the user by (i) moving said transparent window in front of said application window, and (ii) invalidating said error input, wherein said error input does not affect operations of the executing process. 8. An error prevention apparatus having a display screen for displaying an application window representing an executing process, and a pointing device for pointing to a position on said display screen, said apparatus comprising: (a) a transparent window control unit for generating a transparent window, and instructing the operating system to position it behind said application window; (b) a transparent window main-body generated by said operating system; and (c) a transparent window procedure for instructing the operating system to move said transparent window in front of said application window in response to the detection of a predetermined operation input using said pointing device, and wherein the overlapping portions of the transparent window to prevent the user from applying input to the executing process, via the application window, that interferes with normal operations of the executing process while still allowing the user to see the application window. 9. A storage medium for storing a software product for error prevention which is executed on an apparatus having a display screen for displaying an application window representing an executing process, and a pointing device for pointing to a position on said display screen, said software product comprising: (a) a program code for instructing said apparatus to generate a transparent window and position it behind said application window; and (b) a program code for instructing said apparatus to move said transparent window in front of said application window in response to the detection of a predetermined operation input using said pointing device, and wherein the overlapping portions of the transparent window to prevent the user from applying input to the executing process, via the application window, that interferes with normal operations of the executing process while still allowing the user to see the application window. 10. A storage medium for storing a software product for error prevention which is executed on an apparatus having a display screen for displaying an application window, and a pointing device for pointing to a position on said display screen, said software product comprising: (a) a program for instructing said apparatus to generate a transparent window and positioning it behind said application window; (b) a program code responsive to the detection of a predetermined operation input using said pointing device for instructing said apparatus to execute a process corresponding to said predetermined operation; (c) a program code for instructing said apparatus to move said transparent window in front of said application window, and wherein the overlapping portions of the transparent window to prevent the user from applying input to the executing process, via the application window, that interferes with normal operations of the executing process while still allowing the user to see the application window; and d) a program code for instructing said apparatus to move said transparent window behind said application window after the execution of said process terminates. 11. A storage medium for storing a software product for error p revention which is executed on an apparatus having a display screen for displaying an application window, a pointing device for pointing to a position on said display screen, and a timer, said software product comprising: (a) a program code for instructing said apparatus to generate a transparent window and position it behind said application window; (b) a program code responsive to the detection of a predetermined operation input using said pointing device for instructing said apparatus to execute a process corresponding to said predetermined operation; (c) a program code for instructing said apparatus to move said transparent window in front of said application window, and wherein the overlapping portions of the transparent window to prevent the user from applying input to the executing process via the application window, that interferes with normal operations of the executing process while still allowing the user to see the application window; and (d) a program code for instructing said apparatus to move said transparent window behind said application window in response to a timer interruption that occurs after a predetermined time elapses since said transparent window has been moved in front of said application window in said step (c).
