I'm in your chatroom now and the bugs aren't fixed, although it seems like you did upload the new applet (by the way, some smilies are in the UBB default way, like "
")
Also I suggest you in your Chat Settings (in the control panel)'s "Username" field type something short (like "cman"), cause the IRC server is making problems.
Edit: I checked in my board and the fixes do work there... (2.7.1 beta ofcourse) I compared and you have the same version as I have for all 3 applet files.. very odd...
