Created attachment 151123 [details] A page with two div and a jscript function to sync the onscroll event Here you can see the actual results (remember to user Mozilla under a Windows instalation to see the bug in action).
Please report DOM bugs against the DOM, not the JS engine. Someone with a Windows box will have to confirm this. /be

The testcase WORKSFORME: I get the expected results. Mozilla 1.7 final release (build 20040616) under XP Pro SP1a here.
confirming, Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.8a2) Gecko/20040619 using the slider in the scrollbars, the scroll is perfectly synchronized, but using the arrows at the ends of the scrollbars, the one which is activated scrolls smoothly, the other which should be synced, is jumping, about one-and-a-half lines if scrolling vertically, or about two characters if scrolled horizontally. Thats a rough guess, can´t be seen so exactly. This happens in all directions, up, down, left, right. Seen on a slow Celeron 333, but scrolling using the sliders was fast and perfectly synced, only scrolling using the arrows at the end of the scrollbars was showing this bug.

(In reply to comment #4) the one which is activated > scrolls smoothly, the other which should be synced, is jumping, about > one-and-a-half lines if scrolling vertically, or about two characters if > scrolled horizontally. Ok, I also notice the behavior described in comment #4 when and only when smooth scrolling is activated (Edit/Preferences.../Appearance/Use smooth scrolling) otherwise I don't notice it and get the expected results. This is important to explicit and this differential behavior is consistent here.
Confirmed the behaviour of <a href="http://bugzilla.mozilla.org/show_bug.cgi?id=247531#c4">comment #5</a> in Mozilla FireFox 0.9 (Win XP SP1 SPA).
Summary: onscroll event sync over two divs is wrong under win → When smooth scrolling is enabled, synchronized scrolling of 2 divs is jerky
So is the issue that the intermediate smooth-scroll stages don't fire onscroll events? Sounds like it to me...
