     I can only think of two reasons off-hand.

 1)  There might be a virus on your system, because Windows 3 seems to keep
contstant watch on the swapfile, and if a DOS virus changes it, Windows
will, of course, bomb.

2)  I haven't really heard of DR-Dos 5.0 too much, but keep in mind that
WIndows is a microsoft product designed to be used with MS-DOS or PC-DOS. 
It might overrride some of the other DOS functions, or use some other
procedure than interrupts to preform I/O tasks.  Perhaps you should try MS-
DOS and see if that helps.
