Becomes unresponsive for 80 sec when hitting "ctrl -shift-O" for "options"

Tags: #<Tag:0x00007f9788604088>

Every time I want to open “options”, Cantabile becomes unresponsive for more than one minute, then opens the Options Page. The same often happens when shutting down Cantabile.
It happens even if I have created a new (empty) song.
I’m using Cantabile solo 3, build 4041.
What to do?
(will my license key still work as long as I use that old build)?

Hi John.
A similar thing happened to me some time ago.
Try to see the Background Rack, in my case I had to delete all the contents, due to a loop. Cantabile (in my case obviously), he couldn’t find something to “close” and slowed down a lot.
