text: mouse only moving right and left? i have a toshiba tecra laptop running windows 2000.  it doesn't work with an external mouse so i am only using the one on the keyboard.  lately the cursor will only move left and right, which of course is no good.  i have tried uninstalling the driver for the os/2 mouse,  sometimes the mouse will work for a few minutes if i can the mouse setting in the bios from auto to simultaneuos. what can i do to fix this once and for all?
