I suspect that some kind of interaction between different positioning types is a factor. A major problem for pure CSS menus. This problem is new to FF4. Reproducible: Always Steps to Reproduce: 1.Goto http://www.mubulaw.com/ 2.Hover over one of the "practice areas" or "about us" menus. 3.Move the mouse very slowly through the menu options and watch :hover cut out as you cross the edge between the elements beneath the menu. Actual Results: Menu vanishes abruptly despite hover. Expected Results: Menu does not vanish until mouse is removed from menu.
