controller issues?

Some of the games I play, whenever I go to move my controller to select something or type a name, etc, the icon will continue to move some even after I have let go of the controller.

I have the software that came with the joypad, though I have not installed it, as I'm not sure if I still need it since my system has already installed the drivers.

The sensitivity in the Settings menu seems to be calibrated alright.

Is there something in JNES to adjust sensitivity, or do I need to install the software that came with my joypad?

I have a Gravis Gamepro Eliminator 10-button programmable joypad.

Thanks for the tip

I installed the software and was able to adjust the sensitivity. This seems to have corrected the problem as I have noticed an improvement in maneuvering the controls.
