I don't know if these are already known but I thought I'd make my first post in the forums (yay!) a useful one!
when someone types one message that's longer than the chat textbox the scrolling breaks somewhat in that the last line isn't displayed automatically until restart of client.
(hope I'm making myself clear here ;\ )
and also when someone is typing very long line covering more than width of screen the text doesn't wrap, it just gets cut off at ends of screen.
(btw; great work on the game, guys!)
