I'm convinced that it's hardware related. When the screen is up the mouse jumps to the lower right corner and when it's down it jumps to the upper right corner. Both spots are near the delete key. When I move the screen half turned, it stops completely.
The computer seems to get hotter than it used to, and it's all concentrated in that same corner where the vents/fans are, so I may take it apart and clean out the dust and see if that helps.
That's what my thought is as well. I tried cleaning, but it doesn't seem to help at all

Thanks a million plus. Your solution worked like a charm. I tried some of the other solutions in the forum, but none of them worked. I was about to give up and said let me try disabling the pen...and it worked like a charm.
Best wishes...:smileyvery-happy: am a happy camper

I've been having the same problem with my TC4400 tablet running Ubuntu Linux.
Here are my experiences:
- the cursor started jumping about 5 months ago. The computer is in my hands for exactly 2 years now, but it was a renew, so it's some time older, maybe half-1 year.
- the cursor first started jumping to the bottom right corner.
- it had a tendency to jump when I was using firefox watching sites like gmail or youtube, that used Java and/or Flash.
- about 2 months ago it started jumping (and clicking of course) not only when I used firefox with the mentions conditions, but also for other programs, and generally, at any time.
- about 1 week ago, I installed the newest version of Ubuntu (10.04), and since then the cursor started to jump to the bottom left corner too, so now it jumps to 2 different places.
- I also noticed, that the cursor does not jump when I use the pen. (there is no touch recognition, only the pen)
- I also noticed, that my computer started to became awfully hot at the corner of the ventilator, which is the corner, where the ESC button is.
So far I thought about disabling the touchpad and use the joystick instead, but they disable together, so I cannot do that.
I cannot afford to be without my computer, so I cannot put it to repair service. (I had a painful experience with them already anyway.)
The only way I can avoid the cursor from jumping is to hold the pen with one hand to the monitor, but this is pretty uncomfortable.
This whole cursor jumping thing is really annoying, and I'm relieved that I'm not the only one experiencing this.

I've removed the keyboard and the plastic panel beside the keyboard (beneath the screen) to reveal the motherboard. In the area that the mouse would jump to when the screen was rotated and lied down (convertible position), I placed some material (this spot happens to be in the corner where the processor fan is. I'm thinking the fan is emitting some electro magnetic field or something)
I placed a thin foam insulating pad that I salvaged from a dead hard drive and then a folded pieceof aluminum foil in the same shape and placed it on top of the foil. I think bare aluminum foil may be a little dangerous and risk shorting some circuit.
I've noticed the problem a couple of times in the last couple of months but it's pretty much gone. Maybe a 95-99% reduction.
Anyway, to Angelofdarkwind, if you don't need the tablet function of your laptop, you can disable both the touch and digitizer to eliminate the problem. I have no idea how to do these things in Ubuntu but I'm sure there's info on their forums.

I followed your experience, oxfordy, that of disabling the Wacom HID Pen. It appears to work for me.
Many kudos for your "(wrestling) with this problem for months". I have a Pavilion tx2114ca tablet pc running on Vista 64.
I had spent countless hours with HP technical help. (They just follow what they are told on their screens without any real intelligence on their part. If this... do that.)
I had updated everything including uninstalling and reinstalling.
I had gone so far as doing a full reinstall of my operating system, at HP's recommendation, requiring reinstalling all my programs. The reinstall worked...for awhile. Then my system did auto updates of Microsoft software. The "mind of its own" cursor reappeared. I am not a techie but I am led to believe this problem is software related and is a conflict with HP software versus MS operating language.
May I say again, many kudos to you.

I found the answer:
Download the N-trig duosense firmware update. You can download it specifically for the HP TX2 in the dropdown menu.
Hope this works for you as it did for me. The pointer stopped jumping to the top right hand side after the firmware update.
