I have the problem, that when moving the mouse pointer over a input field in firefox browser, the mouse pointer suddenly jumps into the field and when moving the pointer over the field suddenly jumps out of the field again. I have Linux Mint 14 installed. The "Jumping" happens not only with the USB mouse but also with the touchpad.
First I thought that the optical mouse was maybe situated on a dirty pad but the "Jumping" only happens exactly on the edge of a input field. Beside that the movement of the mouse pointer is working precisely.
Anyone knows what there could be the matter for that?
