There's a graphic problem with Jack Orlando.
I have attached a screenshot which shows the setup program. GAMEMENU.EXE produces similar output.
I noticed the same problem already some time ago with the 16-bit vesa patch.
However in-game movies (like the intro) work correctly.
AFAIK Jack Orlando uses VESA mode 0x110 or 0x111.

Additionally when I try to run GED.EXE (the real game executable) DOSBox quits. I tested it with different cores but the result was always the same.
I have attached the error output sent to DOSBox' console.

I'm using recent DOSBox CVS without any patches.
