Keyhandling on FF2/Mac, autocomplete issue

Keyhandling on FF2/Mac, autocomplete issue


Hi devs,
I just fixed most outstanding bugs in the autcomplete plugin, but
there is one issue that I can't reproduce and therefore have no idea
how to fix: http://dev.jquery.com/ticket/2761
According to that, the event.preventDefault() call inside the
keydown-handler doesn't work and the cursor is still moved. I don't
have a Mac and therefore can't reproduce it, nor do I have any idea
how to fix it.
The keyhandling implementation is here:
http://dev.jquery.com/browser/trunk/plugins/autocomplete/jquery.autocomplete.js#L92
Any ideas or just some testing are very welcome!
Thanks
Jörn
