This happens to me too, regularly. Only it's the bottom left part of my screen. Usually a reboot clears it up. It's annoying and I assume it's a bug in the N-Trig drivers for Windows 7, which I'm using.

This also happens on my machine. Can't figure out any regularity in it but it occurs since I installed the N-trig 2.59 drivers.
Under Windows Vista it appeared most of the time when the screen was pretty dark, for example the end titles of Family Guy. There always this little crosshair from the digitizer showed up and jumped between the two microphone holes.
Now with Windows 7 it randomly occurs while surfing on the internet and also while the screen is only showing the desktop. The difference now is that the mouse logo shows up and performs clicks instead of the digitizer. Also the region of clicking changed to the lower left and upper right corner.

Adrynalyne said: Yeah, its a "feature" of the craptastic 2.59 drivers. Dell has newer out, but HP is dragging their feet as usual.

Have Dell's updated N-trig drivers mitigated the problem on the Dell machines?

 If so, then that gives us something to look forward to as well.

Adrynalyne said: Yes, but at the cost of touch points. The Dell only has two now :( ]

2 simultaneous touch points is really enough for most applications.

As long as the new driver introduces stability while still maintaining those 2 touch points, then Im all for it.

spaid said: agreed! I haven't even used touch since the novelty wore off onto my screen. I just want the pen cursor jumping fixed. I don't care if it's single or no touch at this point!!!

Heh, to each their own I suppose :)

 I love the touch for when in tablet mode for browsing the web or ebooks personally.
