Warning -this probably depends on your machine. I haven't had any problems, but Alison's been in there and it crashed her system twice. The only way to fix it is to do a complete re-boot of the computer.

It's fun though - I'm in there with Aine, Kendall, longhair and Jon Freeman. Alison and Alan of Oz were in there until Alison's computer crashed, singing and talking - it's amazing.
