Some mouse drivers have extended video BIOS stuff in them for writing to
EGA registers (since the original EGA registers were read only).  If you
have code that doesn't make use of these calls, that might be part of the
problem.  (ie, code that talks straight to the EGA hardware itself can 
have problems with some combinations of display cards and mouse drivers.)
