Hello, I have a problem with my World of Minecraft I just installed. I'm using Ubuntu 13.04 and World of Minecraft.sh opens and launches correctly. I'm just wondering why I cannot move my mouse down or anything, The mouse seems to be stuck on one side (Bottom corner) of the screen.

Please help.

Things I've tried:

-Don't loose focus hack

-Repacking Minecraft,jar with new l.class file

Here is a screenshot of what it's stuck like:

It just stays like that and spins in a circle while still looking upwards, no way to bring it down.

Also, i'm pretty sure when I click it shows the menu...

Maybe Don't loose focus hack is outdated?
