Summary:could this be the reason?



I was just reading of a math co processor bug that could explain why
some of us have problems with WINDOWs 3...

Apparently there is a timing error associated with a POPAD command in
some?  387 chips.    I was reading in comp.binares.ibm.pc and someone has
come up with a program that checks for this problem.  It seems that MOST of the
machines tested failed.  Since this command is used to push/pop all 32 bit 
registers, it occurs to some this could be the problem with Windows in certain
386 machines.  Could a similar problem be the reason for occasional 
"Unrecoverable..." errors in 286 machines?

I guess one question we could ask is;
        How many out there with unexplainable windows problems are running
        387 equipped 386 machines?
