Sometimes, the messages from my pet rock don't come through. I'm notified of messages, I just can't click on them... and then there's no way to read previous messages.
I am using Chrome in windows.
btw, this was the first time I got to play, and I'm already hooked. My friends saw my screen, and when they saw I bought a house (they're old UO guys) and milk butterflies, they were hooked too. Can't wait for the next tests.
