Forgot addding something: Mozilla/5.0 (Windows; Windows NT 5.1; rv:2.0b3pre) Gecko/20100730 Minefield/4.0b3pre ID:20100730040228 and "* move the Mouse Pointer vertically up and down *and* use your Mouse Wheel to scroll Up & Down" should say: "* move the Mouse Pointer vertically up and down within the Dropdown *and* use your Mouse Wheel to scroll up & down within the Dropdown.

Is this still happening? If it was, I'd expect to see more reports.

I can reproduce on Windows 7 Classic and Aero both. http://hg.mozilla.org/mozilla-central/rev/cf0088ff07f2 Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b6pre) Gecko/20100907 Firefox/4.0b6pre ID:20100907041859

I think bug 599113 will fix this.

Bug 599113 landed so this should be fixed in tomorrow's nightly.

Anyone confirm that this is fixed?

I honestly have to admit that the Issue has been mitigated (though not resolved completly) stepwise before Bug 599113 in the past Builds since Mid Sept. (definitely after the one mentioned in Comment 4). With Build http://hg.mozilla.org/mozilla-central/rev/19cb42fa4554 i cannot repro no matter how hard i try :-).
