Dead on, thanks!  The definitions of tmp and temp in /etc/profile result
in a double definition of the %TMP% and %TEMP% dos variables from the
.Net applications POV and it's too dumb to handle that gracefully.

So the solution is, either we drop the tmp and temp definitions in
/etc/profile, or old .net apps should be started only after calling
`unset tmp temp' in bash.

Btw., tmp and temp are not preserved this way in tcsh's profile scripts.
So I'm wondering why we do it in /etc/profile.  Can somebody give me a
management summary?
