"Open Recent" prevents access to file menu
Under the file menu there is a "recent open" option.
The list for "recent open" appears to be unlimited. When you open the file menu and move you mouse over the list of options (new, open, open recent, close, etc...) the "recent open" option brings up the list of "most recent files". But if that list is long (On my setup, that's about 36 files) it covers over the file menu options (new, open, open recent, close, etc...) and you're not able to access them. This prevents the user from accessing the file menu options using a mouse.
To get around this, I've have been open the file menu and then using a hot key sequence (ex. CTL-S for "save"). But hot keys are not available for all options.
Perhaps the easiest solution is to limit the "open recent" list size or place "open recent" at the bottom of the file menu list.

CLEAR OPTION:
I saw this online...
The Scores section of the Home tab (which opens by default when MS4 is started) shows a "New & recent" section that provides a button to start a new score, or to select a score that was recently open in the program. This list is also available from the main menu under File --> Open Recent. When selecting Open Recent, the bottom of the menu provides an option to "Clear recent files".
.... but my list does not have a clear option.
BTW my version is...
