Using Vegas 9 Pro, I applied an add-in effect (color corrector). When I dragged a preset to the track it popped up a color wheel window where I could adjust the preset. I did something (not sure what) to close that window, and now when I drag any preset to a track it is applied but no adjustment window pops up. What do I need to do to get the pop-up adjustment windows to come back? I have tried everything I can think of!
