I experienced a 'bug ?' in GRX 2.3.2 video handling: when you switch back and forth from DOS box to Windows (Alt TAB) the color table / color palette using 256 GrCells is spoiled. i.e. not the contents of the Cells are disturbed, but their resulting color on the screen. Does anybody know about a fix for that problem ? I think it should be possible, as in Allegro for example, it does not occur. And basically IMHO they should do something very similar, but I am not an expert. Thanks for any hints from you experts. -- Gruss Waldemar Schultz.
