Okay I took delivery of my digitalww touchscreen controller and panel today. Tested in the house, all works peachy. Plug into the car, in the same computer, everything same except the power source, and it works really odd.
It does "work", but I can't calibrate it within the car. Also when doing the drawing test etc, it seems much slower.
Anyone had this before? Although power is the only difference (car battery -> 12v 5a regulator -> Morex PSU instead of AC brick -> Morex PSU) I can't see this really being the problem (according to the specs the controller only draws max 100ma).
I would take it back inside and run a volt meter on it find out what the amps are when match it in the car. if that is not the case then I would check all the connections then recheck with a voltmeter and make sure that you are getting that voltage

Managed to calibrate it with screen off and I can "press" stuff now, just dragging etc won't work until I get a better power source.
