I have iMovie 08 running on a Macbook 2.16 GHz with 2GB ram. After successfully importing video from a DVD+RW I spent a few hours last night deleting many clips. I selected the portion of the clip or the entire clip that I wanted to delete, then right clicked and hit Reject Selection. This was working fine for many hours last night. Today when I resumed deleting I went through the same steps, but the selected clip would not delete. Instead I am getting a red colored red line at the top of the frame window. I have also tried Rejecting the selection from the menu bar and only get the red line at the top of the selected clip?

Any suggestions would be appreciated.
