Hi, I’d recommend checking the PM.log file for clues.
1) On the PM taskbar, select ‘Help’ then ‘Reveal Support Data’. This will open the folder where PM stores its’ logs (and create a zip file which you don’t need for the moment.)
2) Add the PM folder opened by #1 to your bookmarks/favorites.
3) Open the PMDebug.txt file with a text editor, and turn on COPY_MOVE_LOGGING (change the OFF part of the string to ON)
COPY_MOVE_LOGGING OFF ---> COPY_MOVE_LOGGING ON
4) Run a Copy/Move test and write down the start/end times. You may wish to start with one file, then expand to multiple if needed to isolate the problem.
5) Open PM.log with a text editor. Navigate to the start time for your Copy/Paste test and look for log entries that might explain what’s happening. I attached a copy as an example for both a "copy" command and a "move" command.
6) When finished troubleshooting, un-do the change made in step #3.
