Michael Bicha to Sam I came across further issues with SDL 1.2.14 on win32 in combination with touch screens. When you touched the screen older SDLs reported SDL_MOUSEMOTION to the touch position SDL_MOUSEBUTTONDOWN at the touch position 1.2.14 reports SDL_MOUSEBUTTONDOWN at the last mouse position before the touch and then a SDL_MOUSEMOTION to the touch position I found that to fix it in the file SDL_sysevents.c i had to put back the following lines from 1.2.12 to get it working correctly again: if ( mouse_relative ) { /* RJR: March 28, 2000 report internal mouse position if in relative mode */ x = 0; y = 0; } else { x = (Sint16)LOWORD(lParam); y = (Sint16)HIWORD(lParam); #ifdef _WIN32_WCE if (SDL_VideoSurface) GapiTransform(this->hidden->userOrientation, this->hidden->hiresFix, &x, &y); #endif } posted = SDL_PrivateMouseButton( state, button, x, y); where there was only posted = SDL_PrivateMouseButton( state, button, 0, 0); in 1.2.14 (appx. line 484) please feel free to put that change into any SDL lib you like in any way you like and thanks for your great work !

<P>
This library is designed to make it easy to write games that run on many
different platforms using the various native high-performance media interfaces,
(for video, audio, etc) and presenting a single source-code level API to
your application.  This is a fairly low level API, but using this, completely
portable applications can be written with a great deal of flexibility.
