John, assuming you're using 'prototype' for your AJAX, it has a
"evalScripts: true" parameter - have you set this?
If not, you may be running into the same problem that this parameter
tries to deal with.
Either way, I would suggest converting your code to use prototype.
You can then call your <div> content in a single line of code, and not
have to worry about what's going on in the background too much.
Rob.
