The chat upgrade is complete. Hopefully this newer version will eliminate that weird lag a user starts to encounter after they've been in chat for a while.
Regardless, since I upgraded the chat room ALL USERS MUST PURGE THEIR FLASH CACHES!!! This is done very differently from purging your browser cache. I have created some instructions on how to do this very thing and you can find them by going to this thread and following the directions there. Failing to do so may lead to the chat room behaving "funny" on your end or (maybe) even not working at all.
