I have a project (running fine in 2.2.64) that if I open and use, then jusy leave idle for approx 30 mins, does not allow me to go to a different song.
The song it is on plays fine, but clicking with the mouse on any other songs in the project has no response. If I close and reopen it works again, but if I leave it idle I get the same issue and it appears to make no difference which song it is.
