the above page which consists of big image map with 70+ areas, scrolls very slow.
i'm using 2001061221 linux nightly build.
when i load imagemap image in new window alone, it scrolls fast, as usual.

Steps to reproduce:
1. load http://www.kommet.spb.ru/station/index.html
2. decrease vertical window size until scrollbar appears
3. try to scroll the page with either mouse or keyboard
Confirming issue in the June 13th build (2001061308). Use the up and down arrow
keys to scroll page for full effect..

Still slower when scrolling through imagemap by up/down keys.
For a full effect reduce the height of mozilla window.
Not that slow though, on my P4 1500GHz ;)
Build 2002012202, Windows 98.
