It can easily be reproduced by using Bugzilla's Product Dropdown, too. Mozilla/5.0 (Windows; Windows NT 5.1; rv:2.0b3pre) Gecko/20100730 Minefield/4.0b3pre ID:20100730040228

I can't block on this until someone can confirm it.

If Alice says it's a bug, it's a bug. Especially if someone else sees it too

I'd guess this is bug 579736. XtC4UaLL, maybe you're seeing a different bug? This bug is not about combobox dropdowns.

I did see similar issues on the urlbar dropdown, so *perhaps* the combobox is the same issue, too.

XtC4UaLL: oh, missed that you saw that on NT. Thanks for filing.

I can not reproduce on latest hourly build any more. Thanks fix it. Mozilla/5.0 (X11; Linux i686; rv:2.0b3pre) Gecko/20100730 Firefox/4.0b3pre ID:20100730212150
