[ubuntu] Mouse Jumping to the Corner, and click buttons

While searching I did find other people with mouse problem but not the same problem. Majority of the posts I found had involved a laptop and/or touch pad, and the rest seem to be about virtualization. I have a desktop and a normal mouse, and I was ruing the live CD. My intent is to setup a dual boot system.

Also, I don't understand quite how I would fix it. I had to hard reset because the mouse is also clicking by itself.

Anyone can shed light on what the issue is? And how do I fix it ( I mean the process, with the mouse acting all fuy)?

-Thanks
