Yeah, my mouse does that too occasionally but it's never been a real problem with this laptop I've got now. I do need to say that when in sleep mode, I can hover over my desk even with a duster and it will activate. I do find it very disconcerting, but I figure there must be something I've not corrected. Seems to me these days that we need to be really, really careful and read all the information about what we're using. There seem to be so many tricks.
