can't see cursor

Hello everyone,
I have what might be a very silly and simple question, but I haven’t been able to find an answer to it as of yet - when I am typing in the main window in Scrivener, I cannot see the cursor when I type or when I click somewhere in the text. I can still type and do everything, but I have to guess where the cursor is/count the number of times I hit backspace to predict its new position sometimes. Also, when I open the document I’m working on in full screen mode, I can see the cursor for maybe 5 seconds, but never again after that. Please let me know if you have any suggestions! :question:
Thanks a lot~
