I have some users who report that their screen goes blank after they  
minimize then maximize a program that uses SDL.

I know I receive a SDL_ACTIVEEVENT and SDL_APPACTIVE when this happen  
but I'm unsure on how to handle this? Should I call SDL_SetVideoMode  
an reinitialize SDL after the app is maximized again?

The latest users who had this problem was using a  ATI Radeon 9800  
Pro 128Mb graphics card running Windows XP. We tried with SDL.dll  
1.2.8 and SDL.dll 1.2.11.
