I just tried to set the colors in SAX2 (X11 Config) to 24bit (16.7 Mio. colors), and now ACDSEE is displaying proper colors again. I used 16 bit, 65536 colors before. I'm still getting some error messages: ernst@Concordia:~> wine "C:\Programme\ACDSee32\ACDSee32.exe" err:xrender:get_xrender_format_from_color_shifts No XRender format found! err:listview:LISTVIEW_WindowProc unknown msg 1045 wp=00000000 lp=0032fae8 err:xrender:get_xrender_format_from_color_shifts No XRender format found! err:xrender:get_xrender_format_from_color_shifts No XRender format found! There should be some autodetection or at least some warning, that the XRender stuff probably needs 24 bit color depth.
