It seemed to work fine for us, on Macs (os9, osX - NN / IE) and PC (Win98, NN / IE). If you're getting java exceptions, try rebooting your machine and clearing your cache. It could be that the particular Java version you have on your machine is buggy. We had about 50+ people in last night's chat, and all seemed to go well. It sure functions better from the admin side than the old one did.
SFOJFK, let me know if you continue to get those errors...
