TX2 screen not working well with stylus, fingers good.

[Mokusatsu]

I have a TX2 which has had a rather chequered history. It's currently on its third screen, the first two being replaced under warranty for lack of responsiveness to touch (first one) and then the replacement one died completely not long after.

The new screen has developed another problem which I am hoping is driver software related or something.

Finger touch, including multitouch, works just fine. Accuracy is good.

Stylus input is another matter.

It still picks up the stylus, and accuracy seems good because I can point and tap with it perfectly accurately.

The problem is that I can't really write or draw with it. Pen strokes come out as a series of finely dotted lines, or not at all.

When I open MS Paint or Onenote (or anything really) and attempt to draw a line or something what will usually happen is the line will peter out after a couple of cm and the rest of the stroke won't display at all or, if I move the stylus slow enough, it will come out all rough looking, unlike the smooth and continuous strokes I get if I just stroke the screen in the same way with my finger.

Sadly, the thing is now well out of warranty, HP said my latest screen (which was installed a short time after the warranty expired, only after much complaining and escalation of my complaint) will be the absolute last one they replace.

 Any suggestions of how I could fix this would be  greatly appreciated.

I'm running Windows 7 Home Premium

I have discovered that this IS a software issue.

I downloaded the n-trig drivers v 2.239 again and reinstalled. There was a problem during the installation and the computer shut down, then when I booted it up again I found that:

a) the pen worked perfectly!

b) multi-touch was broken!

So I downloaded the file again and tried to reinstall. This time I got various error messages while trying to run the driver installer.

When I rebooted it had rolled back to the previous driver and once again I had four-way multitouch and a poorly working pen.

I think I'll try to run the older driver, before it was 4-touch.

Just an update on my further adventures...

Reinstalling the latest drivers caused a fatal error, i found though that it had been installing multiple copies of the driver. In device manager there were a whole bunch of N-trig devices installed under digitizers.

I deleted (and removed drivers) for all of them, rebooted and tried a fresh install of the latest N-trig drivers from this site.

It still gave errors. On reboot the computer reverted to the default single-touch drivers, with which my pen works perfectly.

I deleted the drivers again and tried the previous (2-touch) version. The install apparently went fine, but while this gave me dual-touch, the pen once again was rubbish.

So I'm now back to using the default drivers which Windows installs. Pen works well but I don't have multi-touch.

Can anyone advise me on how to proceed from here?

Yes, I do want pinch zoom and other multitouch features, but I want the pen to work as well!
