Lose ability to select items, expand pallets, etc. -- all click events.

See screen recording: https://drive.google.com/file/d/1oxhfS-YjJ2JEJkshjUwJrLHBtZFJGP9A/view?…

I opened a file and attempted to expand a palette. The palette does not expand. I close and reopen the file. The palette now expands. I'm able to drag one time signature to a measure, but unable to drag another. Palettes will no longer expand.

This happens with all actions--adding clicking on a measure to add notes, clicking buttons, etc.

This happens quite frequently, I'll get one or two actions in, then will have to close and reopen because I can no longer click items. Sometimes It takes a few restarts to revive the click action.
