**System Information**
Windows 7 64 bit. Nvidia GT 210
**Blender Version**
2.69.11 # 4789793
**Short description of error**
The problems I describe occur only when using a pen tablet and not with a mouse.
I have enabled continuous grab.
Scaling and grabbing an object and hovering the tablet pen away from 3d view results in massive changes to the operation's values (example: 10 to 600 or more). This becomes almost impossible to control and I always end up cancelling the operation.
Middle clicking and hovering the pen away from 3d view causes the 3d view to rotate like crazy!
Also, I have updated my tablet driver. Radius and opacity control using pen pressure works in photoshop and other apps but in Blender it doesn't work.
Even grease pencil does not respond to pen pressure.
I tried different versions of Blender. The latest one being #4acff9d. None of them worked.
I tried different tablets. None worked.
I tried these in another computer. It's working totally fine.
So something wrong with my system?
What could be the problem? Could you please guide me?
**Exact steps for others to reproduce the error**
Create plane. Press S to scale. Hover pen away from edge of the 3d view.
