This is because you do not ask the graphics card which mode-numbers it uses. There is a function (I believe #0) that retrieves a list of modes that are supported. You can then use another function (i think #1) to check the resolution & color depth of each mode. You can use this to make your program work on ANY card seeing as your fix will not work on every card. -- (\/) Endlisnis (\/) s257m AT unb DOT ca Endlisnis AT GeoCities DOT com Endlis AT nbnet DOT nb DOT ca
