Tuesday I posted the following query (Article 13649):
-----
We are having an odd problem here and I wondered if anyone had any ideas.  
Whenever we return from an application (anything that leaves the main windows 
screen, as far as I can tell) we receive the following error message:

			     System Error

		      Can not read from drive a:  (grave accent over the a)

.

I have been doing some poking around on this since, and have tracked down the 
problem to the TEMP variable.  Now I am very confused...  The behavior is this:
with the variable defined and pointing to a valid directory, the above error 
occurs; with the variable either undefined or pointing to a non-existant 
directory everything works fine.  When I open up a DOS window, nothing appears
to be stored in the directory, so I find this very odd.  At least the error
messages went away, but I worry about what the effects of having the variable
undefined might be.

Any ideas at all would be appreciated (please e-mail and I will summarize 
for the net).  Thanks in advance.
