Touchpad random movement and clicks

[Hassan Ibraheem]

Just installed Jaunty (Fresh Install), and the touchpad is becoming annoying.
While moving it suddenly moves in a different direction.

And Randomly when left clicking it middle clicks instead.
So randomly links open in new tabs in firefox, folders open in new tabs in Nautilus, Tabs close when clicking their title, Random Copy/Paste when clicking... etc.

Tried Enabling/Disabling Tabbing in Mouse Settings, but still the problem exists.
I don't have this problem in Intrepid (up-to-date).
I have Acer Aspire 5610z [ http://img530.imageshack.us/img530/3870/dsc06683di9.jpg ]

Confirming with High importance since the touchpad is pretty essential on laptops.

Though by the way, it seems like if I use tap-to-click instead of using the actual hardware buttons to left-click, I can left-click instead of middle-click.
