Go to that site http://www.southeastasianpictures.com/ and click on any menu item (on the top or the bottom of the page). You will see the <img> object (a square with 'SOUTHEASTASIAN PICTURES' text next to it) moving Expected result: that <img> shouldnt move Firefox 1.0 doesnt have any problem with this, but the trunk seems to handle this html/css scenario quite incorrectly. I'll try to make a reduced test-case Reproducible: Always Steps to Reproduce: 1. go to http://www.southeastasianpictures.com 2. click on the top or bottom navigation bar Actual Results: a floating img object is moving out of its place Expected Results: it should stay at its current location

err, not floating, positon:absolute; object, sorry

so I narrowed the problem down and made a test-case ... the problem is caused by the "overflow:" CSS statement. If its set to anything except the "visible" value, gecko screws up.

hrm, we got the testcase, we know why, please somebody confirm and fix this regression additional info: it's not doing this with the Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8a6) Gecko/20050112 Firefox/1.0+ build

downloaded the 18fev2005 trunk , and the regression is there Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8b) Gecko/20050218 Firefox/1.0+

Dupping forward to bug that's in the right component and has more information... *** This bug has been marked as a duplicate of 282754 ***
