If you do not have either of these controllers, rerun setup, select the upgrade option and under Controller Support deselect EX and SX pen controllers. Complete the software setup and reboot your system.

Important Note: Editing registry values may alter the performance of your system or render it inoperable. Create a backup of your Windows® system registry file before making any changes to these files. Refer to Microsoft Windows® Help for instructions on handling registry files.

If you do have either of these controllers, you will need to edit the registry file. In REGEDIT, browse to HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\TwTouch\Parameters. Create a new string value called SerialPortSearch. Assign a value to the set of COM ports with serial controllers (i.e., “COM1,COM3”). When complete, reboot your system.

Multiple Display Support

This release of the MT 7 control panel supports multiple displays. When installing MT 7, you must select the Multiple Monitor Manager tool to enable this function.

Cursor Does Not Reach Edges of Display

Try calibrating the touch sensor. When calibrating the sensor, be sure you touch the center of each target firmly and precisely. If additional tuning is necessary, use the Edge Adjustment Tab to enable greater ability to touch into corners and edges of the sensor.

Cursor is Jittery

You need to adjust the Sensor Frequency. Choose Sensor Frequency from the Controller tab. Any time you adjust the frequency you should test how the sensor is working and verify you are satisfied with the operation of the sensor.

Note: This option applies to capacitive EX series controllers.

Cursor Jumps or Bounces Suddenly Across the Display

You are most likely touching the sensor in more than one spot at the same time. Be sure to point and touch with one finger only. Keep your other fingers away from the touch sensor. Do not rest your other hand on the display or bezel at the same time.

Double-Click Doesn't Work (not available on Windows® CE or Linux®)

Use the Touch Settings tab to adjust the double-click speed and area. The double-click speed defines how quickly you must touch the sensor for the system to interpret your actions as a double-click. Set the double-click speed in the slow to medium range for optimum performance with a sensor.
