Well, I would guess that this Microsoft software, Intellipoint, or Microsoft Mouse and Keyboard Centre is causing problems (and I assume you have that installed), although I can't find anything on the net about it. I would try, however, to update this software, and if that doesn't help, downgrade to some older version.
And if that doesn't help... well I would try uninstalling it completely. Although I don't know if your mouse wouldn't stop working.
Do you have other java games? Minecraft, towns, wurm maybe? If so, do you have similar issues there?
