Amateur Doug here!!!
In CS 5.5, when I highlight and drag some audio clips, the program freezes and won't shut down unless I power off. Ditto when I cut the clips to paste elsewhere.
I rebooted, same result.
I made a duplicate sequence same result.
I tried to cut the clips, same result.
Any tips would be greatly appreciated, because each experiment requires waiting for computer to reboot so it might be days before I find a workaround...
