I've been running into a bunch of minor glitches over my time with working with this program. I finally found one that I replicated and took some screen captures of.

Scenario.
I had a project I was working on. When finished, I go back and 'insert project' in the beginning of my timeline as a header. I did this, and then after making a bunch of changes, I was pretty upset to begin playback and notice there was a phantom audio clip playing during my header. There was nothing in the timeline where this audio was playing. I've had this happen a bunch before, where things are happening that don't appear on the timeline. So I saved, and rebooted the program and noticed my audio track 1 had been sent to the very beginning of the timeline. Definitely frustrating as that threw my entire project out of whack.

I had to go back to my previous save and re-do everything.. making sure I (thought) I did it right this time. Same thing. Notice the before and after screen captures of before and after closing/re-opening the program.

Also, if I now go back on click on the audio portion, it is still linked with the video even though the video is 10 seconds away.
