Oh you are using the old format. I haven't gotten around to adjust the templates yet for that old format since the script update from yesterday. Try the new skin and let me know if that gives you troubles, too.
Sorry Vlad, can't change to the new skin either. Everything's just stuck. If it's something you have to update, then I can put up with it for a while, though my posts may end up looking a little funny!
I am having the same difficulties. It started yesterday afternoon. No smileys I get strange things in the text box and my replies to messages are all crazy. I am on spring version but when I look at the little chooser box it says purple so I change it spring hoping that is the problem but it is just the same. I have restarted my machine a couple of times thinking it was the problem but I don't think it is. When I click on any of the features like the smileys or text features it sends me to the top of the page. I don't know what I am doing wrong
