Several users run my app under Citrix. Every now and then they say that a user's data gets overwritten with the information of another user. What could cause this?


Note: They have set up separate temp folders for each user. This appears to be done correctly.
Sys(2023) for two users show:

C:\DOCUME~1\TESTFD~1\LOCALS~1\TEMP
C:\DOCUME~1\RLONG\LOCALS~1\TEMP

I made a test program to copy a file to the temp folder, and each user was able to copy it independently to his TEMP folder.

What could I try to avoid the data mix up? Help, any ideas?
