Fixed bug #38 I'm using SDL 1.2.9 with Visual C++ 7.0 on Windows 2000. Here's the setup: my game starts in a window, with SDL_WM_GrabInput(SDL_GRAB_ON) to constrain the cursor to the game window. The mouse cursor is outside of the window when the game launches, and when the window appears the cursor is grabbed and placed at the top left corner of the inside of the game window. At this point, if I click the mouse without moving it, the SDL_MOUSEBUTTONDOWN event's mouse coordinates are (65535,65535).

13 \fBSDL_PumpEvents\fP gathers all the pending input information from devices and places it on the event queue\&. Without calls to \fBSDL_PumpEvents\fP no events would ever be placed on the queue\&. Often calls the need for \fBSDL_PumpEvents\fP is hidden from the user since \fI\fBSDL_PollEvent\fP\fR and \fI\fBSDL_WaitEvent\fP\fR implicitly call \fBSDL_PumpEvents\fP\&. However, if you are not polling or waiting for events (e\&.g\&. your filtering them), then you must call \fBSDL_PumpEvents\fP to force an event queue update\&.
