Your solution would obviously work. But try something else before you do that.
Create a new user, with admin privs. Back off priveledges 1 step at a time till that acct can no longer view like this
Then, do the same with hers, elevate it to admin, and back it down.
You might just find out what the problem is, and in the process learn how to prevent it from occuring again.
If after that bit of troubleshooting, you still find nothing that makes sense, then I agree, nuke her acct after proper
backup of course, and make it again.
Good luck, sounds like you have a fun situation there, no Google searches bring up anything even remotely related
to this type of “bug”. So I’m just leaning to the assumption there’s something amiss account / user side and nothing
else would make sense.
