XP has TWO sets of environment variables: User (Les) and System! The User settings on XP look like the System settings on W2K but the System settings on XP are: TMP=C:\WINDOWS\TMP and similar for TEMP.
The W2K setting is: %USERPROFILE%\Local Settings\Temp for both TEMP and TMP.
I had nothing to do with generating these settings on either system!
I've set the System TMP on the XP system to the same folder that I put my macros in: C:\mythestuff\ and I *still* get Error 8!
