Touch screen double clicks are seen as two single clicks due to position sensitivity

I'm developing an app for a laptop with a touch screen. It displays several low resolution images in Lab View pictures. The operator can select an image by double clicking, displaying a higher resolution picture that fills the screen. Double clicking that image returns to the multiple image display.
It is very difficult to cause a double click event via the touch screen. The two clicks must be located at the exact same point on the touchscreen, or two single clicks are returned. My fat fingers can't seem to hit the same pixel twice.
Is there a way to set the position sensitivity of double clicks in Lab View? in Windows?
Thanks,
Dan

Hi Dan,
      I think this would be an OS configuration-parameter - at least, outside LabVIEW - have you looked under "Control Panel" or Programs for a touch-screen configuration utility?  Here's a link to info re: the Dell Latitude XFR D630.  Note the "Doube Click Area" parameter under "Touchkit Configuration Utility" - Settings.
Cheers!
