I've had this issue several times.
When I come back to Audition after several hours (e.g. next day), it is still open and I can see my project, but wherever I click on within the program - it disappears from my screen which switches to the browser.
It is still open, I can get it back from the Task Bar - but can't do anything with it or in it.
Have to shut it from the Task Manager - as there is no other way available - and reopen.
Is this a known issue?
Windows 10 64 bits. Audition version - 23.2.0.68. Firefox.
