Well, that'll teach us to shoot off our keyboards!!

Huh. That's very strange, but I'd guess when it went direct to Windows, 
the underlying DOS memory manager was not getting loaded correctly. Or 
the config options were different; as I vaguely recall Win3.1 used 
different config options for its DOS shell.

I recall having some rather strange config.sys and autoexec.bat bits to 
deal with something like this, then again I was using DRDOS underneath, 
and while it had more functions, it also had more cranks compared to MSDOS.

Yeah, that way you're also flexible for other projects.
