Shoutbox

I recently switched my mouses around, but i doubt this has anything to do with it as my mouse works fine with eveything else. Just if i go to open a convo by double clicking, it wont work, just clicks once. I open by right click > send instant message, but its annoying.

Can someone help?

Edit: Also, even after removing, reinstalling, rebooting, everything, ive ALSO found out that no one can see me online either! I appear offline to them!

HELP ME!
