Hi, I've been using Vegas for a few years, and initially I was flumoxed by this problem. With Vegas 8 if on the timeline you deleted a clip when the ignore event grouping button was on, both the audio and video portions would be erased. However, in Vegas 9 if you delete a clip with these settings the video part gets erased but the audio doesn't. It gets shuffled up to the left of the timeline and merged with those clips. Seems a bit strange to me. I can see logically the audio and video are different elements in a group, but I found it confusing.
