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).
