Again: Scroll-Bug in Internet Explorer (Win)

Hello folks,
once again, I'm asking you for support: as described in my post of June 19,
IE6/Win does not show a scroll bar even though it would be required if we have
an absolutely positioned element within a relatively positioned one. (See
http://home.pages.at/afishh/buggy1.htm, the text on the right sidebar will not
be fully visible in smaller browser windows. Please also note the yellow
background of the main paragraphs.)

Neal gave me advice to apply height:100% to the containing element. I did so in
http://home.pages.at/afishh/buggy2.htm. IE6 will now display the required
scrollbar, but: it messes up the yellow background of the paragraphs! First, the
yellow is not visible at all. If you scroll down and up again, it partly
reappears. The yellow also reappears if you select some text and unselect it.

Now, the main problem here obviously is that I want to position my sidebar in
relation to a container, not to the body. Can anyone give me advice on how to
implement this best? If not, then I will <jehova />: simply use a two-column
table for that layout...

Thanks,

Alex
