There are some post revolving around onbeforeunload/IE7 and a quick
debugging session shows that no code is ever executed for onbeforeunload
with IE.
Posts suggest that returning values from a func assigned to
onbeforeunload are a nogo and that nulling the func is also leading to
problems.

MS has comfirmed that the onbeforeunload event handler has an issue:

I would be more than happy to move up to the current implementation of
nevow if there is a fix for this problem.python
I brought this issue up on the list last year when testing with IE7 beta
but nobody was able to help ending in a few posts to divmod-dev on

Thanks for your help, Werner
