My brother tried the game for the first time since like, six years ago. Installed java, downloaded the game, and made a new character. He can move the sprite in the character creation area once. He can click ahead to a place and the sprite will move there, and no where else. It doesn't matter where he clicks or how many times but it doesn't do anything beyond that initial click.
The kicker is everything else on the game works. The animation continues, the sound is on, it doesn't appear that the game or client is frozen. All the menus even work.
What's going on here?
