Had something odd happen last night.

I opened up a XDCAM HD project that had been completed in Vegas Pro 8. It was fine, till I cut some clips out and then undid the cut. The clips came back, but were red on the timeline. I then tried loading the same project from before I made changes and got red clips in the same places. I then exited and loaded Vegas Pro 8 and loaded the same project and it came in correctly. I then repeated the same delete and undo and all clips were fine, no red.

I then repeated all this again in Vegas Pro 9 and the red clips didn't happen this time.

But anyway, I was wondering if anyone else has hit this?

Thanks.
