I have the latest version, accept the last update from your post.
I'm running an 3.0.2 forum, and I'm using the latest FireFox 3 version,
my members are using different explorers like IE7, FF2, Opera etc.
And the all are getting the same problems with the smileys and the BBcodes,
I have installed the style on the right way, but there are some errors in the style, it haven't got the files posting_editor (or post_editor) and editor.js
That are the normal files that an style have to have, issn't it?
I don't believe that the style is 100% worked perfect, or I have did something wrong.
