About a week ago, my Finale has gotten harder to click through; a few examples:

• If I'm in chord mode, I now have to click a blank space after entering a chord, then I have to hit the ESC key in order to leave chord mode, whereas I previously could just click the Selection Tool (currently if I hover over the selection tool while in chord mode, it doesn't register that I'm hovering, and clicking doesn't do anything)
• When I enter ":0" with a chord to bring up the suffix selection, if I try to click a suffix, it'll bring up the suffix selection window again (on top of the first copy), and I have to make selections in both windows to close out, but then 2 chords are applied in the same space, one with the suffix and one without.
• When I try to shift chord alignment (with the left-hand tool with the 4 triangles), I used to be able to click directly, but now I have to click a few times in the white space or near the triangles to get my cursor to register.
• Finale now crashes and restarts 3-4 times a day, whereas that would previously happen maybe once every 2 weeks at most.

I don't believe that it coincided with any system updates. Is this something that a reinstall/repair install would fix? I have Finale 2012c for Windows 10.
