Nicely done bus warrior.

Also, under options (button) clicking sound gives you an option to sound volume level. May help hearing noises when someone enters, leaves chat.
I may bring back the moo. I liked the moo noise when someone hit the call button. Back in the day... , we used moo.
I'm not sure about the lockup issue. wonder if an adobe flash player upgrade would help? Right click on chat, about and you will be @ adobe site with a rundown on chat version. Hopefully that is not more confusing... Let me know,
Best Regards, Phil
