Inserted the fish sample movie and split the audio track which went in to the Voice track. Put in a fade at start of the audio and a fade out at the end. I then decided to drag the track in to the Music track - Operation Failed! it said. Now there is no audio track anywhere, it just disappeared.
As an experiment I then split the audio of another movie, which again went in to the Voice track. Dragged it to the Music track - no problem. Seems like PD7 doesn't like dragging where there are fades. Now, with the track in the Music track I add the fades and this time just try to drag further along the timeline. No go. Abnormal termination and PD7 closes with an option to send the crash report to Microsoft.
Anybody replicate this?
