I'm trying to film a short motion sequence out of sketchup for a tutorial I'm preparing. When I click record in camtasia, I am getting a black screen where sketchup just was. Also, in my Windows Task Manager, it shows Sketchup going back and forth between "not responding" and active.

Let's just try a restart.

Not helpful.

What about if I uncheck the "turn off display acceleration" at the end of the recording setup dialog?

That did it!
