File Menu Functions

Hi, and thank you in advance for your help.
I have a persistent problem with the File menu in Musescore Studio 4 in the Scores mode as follows.
When I am in a score file, and engage the File menu, it appears normal. When I roll the prompt over anything after the Open command, the view changes to a list of my score files. I cannot engage Save, Print, Close, or Quit.
Can you help with this?
Thank you!
