Windows 7 touches not seen

Unity Engine
1

Just wondering if I’m missing something obvious, as I’m starting with Unity 4.5. I’ve tried various scripts from the forum.

I have an Acer touch screen, on Win 7 64 bit and it shows 10 touches available.

MS Paint will draw with multi touches.

When I run a scene in Unity and show Input.touchCount it is giving me zero. Have tried using touches on a GUITexture.

Input.multiTouchEnabled appears to be TRUE.

Is there a switch that I need to set somewhere, or some other way to test?

Regards

More confused now…

If I press PLAY in the editor, multiTouchEnabled is TRUE, and touchCount is zero

If I build the app, and run it, multiTouchEnabled is FALSE, even though I try and set it true in my Start routine.
