MEDX2KEY keyboard trackball irresponsive

[palaczk]

Using the trackball to place the cursor exactly somewhere at a webpage is extremely difficult, even having adjusted the cursor speed with the MEDX2KEY downside button.

Whether I roll it hard or I roll it gently IT DOES NOT WORK!!!
You can see tiny little indefinite movements of the mouse icon but nothing as considered to be functioning.

HOW COME???
