I have accidently set up a loop on more than one occasion in vegas movie studio 6 but do not seem able to remove (delete) it. Please does anyone have any ideas?
Generally you can ignore the loop if you don't want to think about it.
You can collapse it by pressing i and then o without moving the cursor. This will create a new loop with a length of zero, which effectively means it doesn't exist.
This might help - go to Options>Preferences>Editing and click the Collapse Loop Region box. If it becomes annoying that way, you can always change it back.
