Hi
Today I suddenly have this problem: When I single click in an empty bar the note input is started! Before I had to double click!
What can I do?
After a reload the project is working again.
A little more info could be helpful! Did you make any changes to Dorico recently? Or any OS updates? Windows or Mac? Dorico version? Anything you might think of as insignificant that you added or changed?
If you’re on Windows, is there an update pending? (That always messes with my system!)

Edit— You ninja’d it! Glad it’s straightened out!
One of the first things that I always try! (That, and rebooting!) Sometimes things just need to get re-initialized. 
That’s of course the way to do it!
