how do I stop iMovie 10 from freezing so often when I'm editing?
When I am editing a video, iMovie regularly freezes, so I have to force quit and start over. [I don't actually lose work, but it's a nuisance starting over so often.]
I'm talking about freezing every 15-20 minutes of editing, so in a 90-min tape, that's at least 6 times!

Thanks for any help offered!
