Avid Free DV: lift and extract buttons disappear from timeline

Hello,

I'm learning Avid Free DV (yes, I have a legitimate copy installed from a disc which came with my Avid Made Easy book by Jaime Fowler) and I'm having an issue with the timeline.

When the program loads, I initially see the timeline as it appears in the book. But then it changes and the "Lift" (weight lifter man) and "Extract" (scissors) buttons are no longer there. According to the book, these features should be present on Free DV as well as Express.

I've tried looking through preferences, and tried all of the possible modes (basic, source/record, capture, etc.)and restored them to default settings using the command in the Toolset menu and can't seem to find a way to return the timeline to its default mode.

Any suggestions would be appreciated.

Best,
Jeanne
