Movie explorer makes Flash CS5 crash

I’m showing movie elements. Say I have a bitmap on frame 2000, I right-click on it, and Flash immediately freezes up then crashes. Sometimes it recovers after freezing for a few minutes. This goes for symbols and audio too. The only thing that will not crash to click on is text.

The movie explorer seems like it would be a pretty useful tool if it would actually work.

How do I fix this?

Here’s what I’m working with.
