It works on some embedded flash videos (like youtube.com) but not on the site I linked to. It works in Firefox 2, IE7 and IE6 Reproducible: Always Steps to Reproduce: 1.Go to URL 2.Scroll with the mouse-wheel when cursor is over the embedded video 3.Notice the immobility of the page Actual Results: The page does not scroll Expected Results: The page scrolls

Could someone please confirm this ?

Confirming on Linux with Firefox 3 nightly build from 2008-02-28 (Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9b4pre) Gecko/2008022804 Minefield/3.0b4pre). When I hover the mouse cursor over the embedded video, mouse wheel doesn't scroll. However, keyboard cursor keys still work for scrolling.

Confirming on both Firefox 3 Beta 4 and now 5 on Windows XP SP2, with Flash 9.0.115. Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9b5) Gecko/2008032620 Firefox/3.0b5 ID:2008032620 Like the OP said, this worked fine in FF2.

i also experience this problem, only on certain flash sites though, more details are. Scrolling over page fine, Mouse scrolling over the flash object BEFORE the play button is pressed doesnt work, but as soon as the mouse is off the flash object, the page scrolls. After the play button is pressed and the flash object is clicked on, the page wont scroll anywhere, without first clicking on another part of the html document first.

Still getting this problem with some sites and videos in RC1. Here's another example page: http://www.videogaming247.com/2008/05/16/five-new-in-game-silent-hill-5-movies-posted/

Can confirm this problem occurs on (all I've tried so far) http://news.bbc.co.uk/ flash presentations - both up and down doesn't work as soon as mouse enters flash display area. Moving back out re-enables it - no click required. Problem only manifests itself after video has loaded - during the load period - flash has already put up its [blank] display - scrolling still works. Try the live bbc news channel link at the top of the main news front page - http://news.bbc.co.uk/1/hi/uk/7459669.stm. I'm running FF 3.0 on Win XP SP3. Does it on XP SP2 too. Standard MS 2 button + scroll wheel mouse - USB. IE7 on the same PC has no such problem.

I can confrim with recent Linux trunk build. Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.1b1pre) Gecko/20080928200351 Minefield/3.1b1pre

Your Bonsai link looks wrong... this one is better I think: http://bonsai.mozilla.org/cvsquery.cgi?treeid=default&module=all&branch=HEAD&branchtype=match&dir=%2Fmozilla%2F&file=&filetype=match&who=&whotype=match&sortby=Date&hours=2&date=explicit&mindate=2006-05-01+04%3A00%3A00&maxdate=2006-05-02+05%3A00%3A00&cvsroot=%2Fcvsroot which includes bug 333166 which seems relevant...
