I have spent hours and hours trying to get preview plugin to work in 1.5 without major mods to core code etc.
I am a newbie and this one worked ‘out of the box’ with just the one line added to comments.php in my theme folder:
http://www.softius.net/wp/plugins/comment-live-preview/
It’s not just automatically deleted spam comments that stay in the database but also those which go into comment moderation and are manually deleted there.
My apologies if this should have gone into ‘Plugins and Hacks’ but I’m new here and I thought all 1.5 issues had to go into this discussion area.
Sorry , I can’t tell you what’s wrong with your sidebar (don’t know enough about html) but I can’t see any difference between the view in IE6 and Firefox
