Fixed bug #526 Comment #1 From Simon Howard 2009-03-20 16:50:56 Hi, I'm the author of Chocolate Doom, one of the other source ports that James mentioned. This is a patch against the current SVN version of SDL 1.2 that fixes the bug. It has been tested and hopefully should be obviously correct from examining the changes. I'll give a brief explanation. When the palette is set with SDL_SetPalette, the IDirectDrawPalette_SetEntries DirectX function is invoked. However, when this happens, a WM_PALETTECHANGED message is sent to the window. A WM_PALETTECHANGED message can also be received if the palette is changed for some other reason, like if the system palette is changed. Therefore, the palette change handler (DX5_PaletteChanged) has code to deal with this case. It distinguishes "expected" palette changes (set with SDL_SetPalette) from "unexpected" palette changes using the colorchange_expected variable, which is set before calling IDirectDrawPalette_SetEntries. However, the code to set this variable is missing in the fullscreen code path. By setting this variable, the palette change is handled properly and the freezes go away.

==============================================================================
Using the Simple DirectMedia Layer with S60 3.x / Symbian 9.x
==============================================================================

These instuctions are for people developing for S60 3.x. S60 3.x
uses Symbian OS so you need S60 SDK.

extract "symbian.zip" into this folder.

go to symbian folder

bldmake bldfiles
abld build

That produces WINSCW and ARMV5 versions of sdl.dll runtime library 
and sdl.lib for development. 
The sdlexe.dll/sdlexe.lib and sdlmain.lib are for easy SDL S60
integration, please see http://www.mbnet.fi/~mertama/sdl.html
for further info.
