Hello, 
I experience massive slowdown while viewing this page:
http://www.k-arvutisalong.ee/Detailid.htm
Especially when i scroll page, text got underlined for some time, then back
normal and again, menwhile browser uses all my proccessor resources.

On this pahe is quite a big list of items(text), my other browser handle it
well, so i thought it could be some bug in proccessing page, sorry if i'm wrong
and wasting your time.

Thank you.

Some system information:
AMD Athlon XP 2000, 512 ram.
I got SP2 installed and all latest updates.
That page is badly written. It uses CSS hover to set an text underline for an
(acccidentally) *very* big element ("ALGUS"). Naturally, underlining that all
takes a lot of time.

<HTML>
...
<STYLE type=text/css>A:link {
TEXT-DECORATION: none
}
A:active {
TEXT-DECORATION: none
}
A:visited {
TEXT-DECORATION: none
}
A:hover {
COLOR: #CC0000; FONT-FAMILY: Ariel; TEXT-DECORATION: underline
}
</STYLE>
<BODY BGCOLOR=#FFFFFF>
<FONT FACE=Serif>
<BASEFONT SIZE="5">
<A NAME="ALGUS">
...A *long* page here...
