I'm stuck at the same "Move the current time marker ...." message. I move the cursor back to start of event, click play and the same message appears, time after time. I've tried enlarging Target and Search areas, but can't get past this.

Another stuck area - I clicked on "Animate" next to the Rotate slider, expecting to see a keyframe mini-timeline or something so I could change the orientation during motion, but clicking Animate had no apparent effect, and I could not work out what to do next.

The pdf documentation is all about how Boris works in After Effects, so I've no idea how this varies in Vegas.
