Click the switch editor mode button on the top right hand side of your text box. Its above the box of emoticons and looks like this:
your screen will switch from gray to white and your cursor will appear. for some reason Firefox defaults the editor to this setting. you can use it to do a quick flip back and forth to preview your UBB codes and what they are doing.
I also am a big fan of google chrome.
Thanks, it worked! The only strange thing now is that I get the Ironman font while I'm writing my post and then it changes to the usual font when I preview, but I can live with that.
