Rev crashes when getting back web pages contents

[Phil Davis]

In my own [unfinished] work with this kind of thing, I found that Rev 
struggles with pages that contain Javascript. If I get a URL, remove all 
the "<script ... /script>" blocks from it, and then set the htmlText of 
a field to it, things move a lot quicker and smoother. I'm not sure if 
that's the final, definitive answer to your problem but it has given 
some relief. But like I said, I haven't tested thoroughly to see if I 
can still recreate the problem after applying this fix.
