Oranghutan 12, that sounds like it is probably a different issue than the one that was causing periodic crashes with PT9.
Here’s something from the PT Help files that might work for your student:
If there are problems with Paratext crashing, it might help to reset the program:
Hold down the Shift key when starting Paratext.
Click Yes to confirm that you wish to reset your Paratext settings.
Do one of the following:
Click Yes if you wish to report a problem (to let the development team know what problems you encountered which caused you to want to reset Paratext).Follow the steps (from step 2 onwards) in How do I report a problem in Paratext? to report the problem.
Click No if you do not wish to report a problem.
Click OK when asked to do so.
Restart Paratext.
Select the interface language you wish to use, and click OK.
Re-open any windows you need to continue your work.
