"Also, the error is indicating that the return file was being locked by another application. Could it be your backup or anti-virus software actively locking or scanning the file at that moment? For anti-virus software, could you please try to whitelisting the ProSeries folders, and anything below, e.g. c:\prowin21."

The error does not occur during shutdown but when opening a file.  When opening a file (on occasion – has happened three or four times this afternoon), I will get the error 2705 error.  I click okay on the error message and then the screen is gray.  I click on the “x” in the upper left and I then have to restart the program.

I will try and “whitelist”  I see where I can do it to a file but not a folder.  I will contact my IT guy for help.
