I get weird stuff with the touchpad on this laptop all the time. Definitely a "feature" which I've tried to kill. It has mouse pad buttons anyway, so I don't need the touchpad for clicking anything or scrolling, etc. yet it keeps trying to do stuff I don't want. Rearranges whole sentences while typing, etc. Drives me nutz -- I think I'm typing someplace and it's suddenly inserting somewhere else.
Yesterday I think I fianlly located the "setting" panel that does two finger/gesture/mapping junk and shut it all down. So far, so good. Typing seems normal now. Fingers crossed, so to speak
