X201 Tablet Pen Problem when on Portrait mode.

[#1]

Question

Stylus works great in landscape mode but when I switch to portrait the pointer moves all over the screen. I can't calibrate because when I open it and it is not responding to any touches on the screen.

Answer

Uninstall ISD Tablet 7.0.2-10 from Programs And Features in Control Panel.

Install ISD Tablet 7.0.2-19 from this link:

Reboot.

I have the 7.0.2-19 installed and the problem with using the pen on all table positions persists. I can only use it with one of the landscape positions and none of the portrait. On the other three positions the arrow moves on the oposite direction of the pen. I cannot calibrate either. An interesting point is that this does not happen all the time and I do not know what it is trigging it. Can you help.
