Thanks for having a look. The sidebar performs the same way on the archive page in Safari and Foxfire as well.
I have only one plug in activated, the feedburner RSS redirect. And the archive sidebar was screwed up before that, so I do not think it can be responsible.
Thanks for the link. A little beyond what I understand right now, but I’ll start poring over it.
What do you mean by “the whole page jumps”? For me it just lists the sidebar at the bottom of the posts rather than the side.
Thanks.
