From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; N; Linux 2.2.14 i686; en-US; m14) BuildID: 2000032711 Sometimes, when I'm viewing a long web page such as the comments pages on slashdot.org, if the Mozilla window loses focus and gains it again it suddenly scrolls to a different part of the page. No matter how far down the page I was reading, it jumps to a spot that's typically about 5 screenfuls down. If I scroll down and then make the browser window lose and then gain focus again, it jumps up again. It seems that it stops doing this if I scroll up past the point it jumps to and then back down. Reproducible: Sometimes Steps to Reproduce: 1. Go to a web page like http://slashdot.org 2. Read long pages for a while, occasionally switching to another window and then coming back to the browser window 3. Sometimes it scrolls way up the page when you do this If you are using a window manager on Linux that gives the focus to the window that the mouse is over, and this effect occurs, try to scroll down while moving the mouse out of and back into the window occasionally. Note how it always jumps back to the same spot. Actual Results: I ended up looking at a part of the page I had already read, about 5 screenfuls from the top. The scroll bar moved there as well. Expected Results: It should have stayed at the part of the page I was reading.
