I've been plagued with erratic cursor movements while typing. The cursor jumps to a new place and typing continues there, or it will jump someplace totally outside the area. I've switched mice 3 times now - same problem with each one. ive changed ports as well. It's driving me mad! Weird thing is, it's only been happening in the last 3 or 4 months and ive had the laptop for a few years so it shouldnt be whether the touchpad is enabled or not. Im on a Gateway laptop with Vista Home Premium. Thanks in advance for any help offered.
