just upgraded to vegas pro 15. I just installed on my computer and have been playing around with my frequently used tools/effects from prior versions. I frequently use the cookie cutter effect to circle something in a screenshot. When I tried this in new program, I saw a half circle, and when I position to the right I can see the whole thing, and it vanishes as i move past midway to the left.
I assume I inadvertently chose to default mask half screen or something. Seems like a basic fix but I can't figure out what I did. Restarting program doesn't help. Thanks for any assistance!
