Certain industry-standard applications such as Photoshop can Painter cannot register pressure of the pen.
This problem appears to be related to the WinTab API not being able to communicate properly with the digitizer output.
Our solution for issues related to the pressure sensitivity and the WinTab API are currently under development and is due to be released in mid-May 2010. If possible we may post Beta versions for testing earlier.
At start-up, the digitizer and/or driver will fail to initialize with various error messages.
At start-up, the digitizer and/or driver will fail to initialize with these error messages:
"Can't Connect to Driver"
"N-trig Applet has Encountered a Problem and Must be Shut Down"
"Digitizer Not Found"
The issue described here is usually as a result of a USB communication error, and is generally fixable with a full shut down/power-up procedure. This was root caused two years ago to be a fault of the 3rd party software that ships with iTunes. While N-trig made some improvements to avoid system hang ups this issue can also be observed on standard non N-trig platforms with both Windows and iTunes installed.

Screen edge pen stutter?
The pen cursor jumps 1-2 inches inward when hovering near the screen bezel. Single pen presses in this area are registered as multiple, successive taps. Input reset does not improve the stutter in the edges.
This is a known issue and is one of the things addressed and greatly improved upon in the latest bundle (2.239) to be released by N-trig – the Dell version of which has been released, and the HP version is due to be released at the end of February , pending HP’s approval.
When inking, cursor will jump from the pen nib to the palm causing a long stroke to be drawn between both points.
This often occurs in the pauses between inking strokes when the user lifts the pen from the digitizer. This problem occurs more frequently when the palm is resting at the edges of the screen.
This is a known issue. A new software bundle that will include a fix for this problem is due to be released by mid-May 2010.
The pen input experiences severe tracking lag or jumpiness over the entire screen.
This problem may be related to the pen malfunctioning. Rooms with strong lighting in close proximity to the screen greatly aggravate problem.
This is a known issue that happens when there is a source of fluorescent light close to the screen. The effect of this issue can be greatly reduced by moving the source further away from the computer. A new software bundle that will increase the noise immunity is due to be released by end of March 2010.
The digitizer will detect false touches at various points on the screen.
This problem can occur randomly as single touches or bouts of random touches. This problem is also seen frequently when the screen is being manipulated, such as adjusting the screen tilt, swivel or pivot. Input reset does not always solve the situation.
This is a known issue and is one of the things addressed and greatly improved upon in the latest bundle (2.239) to be released by N-trig – the Dell version of which has been released, and the HP version is due to be released at the end of February, pending HPs approval.
Touch input will randomly cease to function with no warning/error.
This problem occurs within the first 10 minutes to 1 hour after boot. Input reset does not solve the issue, but a reboot or wake from sleep does.
This is one of the things addressed and greatly improved upon in the latest bundle (2.239) to be released by N-trig – the Dell version of which has been released, and the HP version is due to be released by the end of February, pending HP’s approval.
Some spots of the digitizer will not recognize touch.
This problem may occur when the tablet is not grounded either by touching the case or with an AC cord.

Due to the extremely poor documentation and coupling of the drivers and firmware, many users have become stuck with improper or unwanted firmware that renders their digitizers inoperable or buggy.
We will be posting the rollback procedure, and an explanation of how it should be run on our website. We are currently testing this prior to release, and will post it by mid-February 2010.
The coupling of driver and firmware creates installation difficulties and confusion.
The coupling of driver and firmware creates installation difficulties and confusion. It breaks the standard driver installation structure used by almost all other hardware vendors. The native windows driver rollback and/or system restore features are not usable, and if used, may leave the digitizer in an unusable state.
The N-trig bundle is comprised of three components that are inter-related and linked, and cannot be separated – the firmware, the drivers and host. We are working towards finding a solution to the issues experienced in the future.
The driver/firmware installation problems are also caused by extremely poor documentation.
The driver/firmware installation problems are also caused by extremely poor documentation. The driver install packages often fail with cryptic error messages, such as "Fatal Error" and "Operating system is in adequate for installation". The install packages may also have undocumented dependencies, such as Visual C++. No guidance is given on how to diagnose or restore a digitizer to its proper state. There are no clear indications of incompatibility between driver/firmware versions and difference operating systems or different machines.
N-trig is investigating further how we can improve this situation. Also please see our answer above, regarding the rollback procedure, which is due to be posted on our website by mid-February.
