I posted about this bug a couple of weeks ago, but no one knew the
solution. I have collected all the information I can think of (rhide's
bug report command, the output of mem/c and set, the contents of
autoexec.bat and config.sys, and the stack dump printed when it
crashes)

The crash always occurs when I press a key, but other than that, it
seems to be random.  Sometimes I get two Invalid TSS errors, as in the
traceback at the end of this message, sometimes only one, and
sometimes one TSS and one Page Fault.

FWIW, the system that causes this error is a 486/66 with 16 megs RAM
