My patched GO32 fixes the keyboard problem only for non-VCPI (no EMS)
situations. Try without 386MAX or using the 1.08 extender. Does the 
mouse work? If so then the computer did not really hang -- the program
just does not get the keystrokes.

The orange text is quite normal for error messages. SUIT happens
to initialize its color table in a way that color index 7 (the
regular low-intesity white DOS text color) is mapped to orange.
AFter this anything written to the screen using DOS and the BIOS
appears in this color. The text on the screen should be some fatal
error message from the extender or the program. If unreadable
(Some SVGA BIOS-es don't handle text output properly in HiRes modes)
try redirecting both the standard output and the standard error to a
file. Once you know what the problem is, correct it. Things which
can possibly go wrong:
 
   no 387 and 387 emulator. (SUIT uses some floating point arithmetic)
   wrong graphics driver, card (try the GRX tests, if you haven't done so)
   make sure you are using GRX version 1.02.
   make sure that the GRX font path is set up properly.
