I just plowed my Dell Precision M6400 laptop and installed 64-bit Windows 7. Everything seems pretty good, except that occasionally while I am typing, my caret ends up somewhere else within the text. This is quite irritating, since text can quickly turn to gibberish that way. At first I thought I was just hitting the touchpad with my finger accidentally, but I am now pretty sure that's not it.
I think it might be the touchpad in some way, though. I do not have a driver for it, and the Dell support guy basically told me tough luck until they actually start shipping Windows 7 and supporting it. This problem does not occur when the machine's in a docking station -- it only occurs when it's standalone and I am using the laptop's keyboard, even with an external mouse.
So, how can I figure out what is causing this and fix it? There must be a driver that worked in 64-bit Vista, since that's what I had previously, but I am unable to find it. Dell guy wasn't too interested in this either.
