I'm using touch screen to control my small CNC machine. When I press and hold any button on the screen that move my CNC mill table it goes out after 3-5 seconds and the table stops moving. Then I have to repress and hold the button again to move it more. Is there a timeout or something on the PC?
SAme thing happened when I try to use the slider on the side of document or website. I press and hold down the small arrow to move the document/website down and it stop after 3-5 seconds while I'm still holding the arrow.

I'd like to post this as a Clarification, as it isn't an answer. Need more information from you.

On this touchscreen Computer Numerical Control mill; is the computer WITH the touchscreen, or detached, as in a computer tower?
