I just noticed one thing: I'm using IE9. Sometimes I would get extra lines on my screen while viewing the posts in this forum (still readable, but annoying). The extra lines and slighly malformed characters appeared ONLY when I am on 'the forum'. IE9 works perfectly everywhere else.
At the bottom of the browser window you can select which 'mode' you want IE9 to run in. It lets you choose "IE7 standards", "IE8 standards" or "IE9 standards". I WAS using IE9 standards, but I just switched to IE8 standards. VOILA! Now the forum looks better. Maybe my code posts will work better as well. I'll soon find out.

So, while IE9 works better than IE8 for most everything, that is not true when viewing this forum.
