When editing the source clips in my video project my Chapter Head skip buttons (fwd and bwd) were working on all clips and now they don't!

However, skipping chapters in Simulation mode do work. Did I change a global setting by accident that would turn off these two navigation buttons in edit source mode?

When I click on the fwd and bwd chapter skip buttons in the Source Edit screen they now functionally act like "move to Next Frame" buttons.

Hmmm. This may have started being a problem after I loaded ffdshow Tryout codec dll. I loaded it because one clip I added to my project was just showing a green screen and the ffdshow Tryout made that clip useable.

Anyone had any experience with this?

Thanks!
