If you click and hold the scrollbar (as if you were going to drag it) and drag the mouse away from the scrollbar (which releases focus on the scrollbar) the scrollbar resets to a few pixels above its original location.

Reproducible: Always

Steps to Reproduce:
1. Click on scroll bar
2. drag cursor away from scrollbar

Actual Results:  
Scrollbar goes back to several pixels above original location

Expected Results:  
Scrollbar should go back to original location.

I used a pixel magnifier to test it and indeed, even if I move my mouse in a straight line, the scrollbar moves a bit.

Also reproducible with SeaMonkey 1.0a and SeaMonkey 1.5a/20051212.

This bug still exists in Firefox 2.0 and 3.0a3 (February 8th 2007 branch). To confirm this, find the bottom of a table or image on a web page (move the scrollbar until the image is just out of site behind the addressbar). Grab the scrollbatr with your mouse, drag it to the top of the page, then move the mouse to the left until it releases the scrollbar. It should go back to where it was before, but you'll notice it went one pixel higher. Do this enough times and you'll get to the top of the page.

This bug does not exist on the latest Firefox 3 on Vista. Someone please confirm if it still exists on latest Firefox 3 on XP.
This bug was reported on Firefox 2.x or older, which is no longer supported and will not be receiving any more updates. I strongly suggest that you update to Firefox 3.6.3 or later, update your plugins (flash, adobe, etc.), and retest in a new profile. If you still see the issue with the updated Firefox, please post here. Otherwise, please close as RESOLVED > WORKSFORME
