Build: 2000031512 (and prior versions at least to M14). I can't reproduce this exactly, but it happens on a regular basis. Mozilla will stop scrolling. Symptoms: viewing a page previously loaded, probably after Open in a New Window on another page, the original page doesn't scroll any more. That is, the main pane's display doesn't change. I can click within the pane, and use the arrow keys, and the scrollbar will scroll but the page doesn't change. I can also drag the scrollbar with the mouse - it moves, but the page never scrolls. As if it were ignoring the display updating on scroll sometimes. Reloading the page "fixes" it. I have "gfx scrollbars" and "use ViewManager2" checked in the options box.

Dup of bug 26658?
