>I created two .EXE files. One appfile.exe without Debug and another one appfile_deb.exe, with Debug. Placed them both on the customer server. The main user has appfile.exe on her desktop. But she decided to take a day off today; so I won't find out till Monday. And if she still has a problem, I will ask her to start the application with the appfile_deb.exe. So, hopefully I will find out, next week, the cause of the problem or at least the line number.

Then, you have a relaxed weekend. :)
