W700 touch events getting lost

I wrote a couple of programs that get started when the tablet boots up.  They run the entire time the machine is powered on.  They are .NET 4.0 WPF applications.  I have this installed on many W700 tablets that have been distributed throughout the world.

 

For some of my customers they experience a condition where the touch events to the applications stop working.  If they connect a mouse, all the controls work fine, but the touch events don't do anything.  

 

If they swipe from the side, the charm bar will come up, along with subordinate choices (e.g. control panel).  Also, any touching on the desktop seems to work.  They can start other applications that respond fine to the touch events.  It is only my applications that seem to be ignoring the touch events.

 

I don't know if I've done something wrong in my program, or if it is a .NET or WPF artifact.

 

Any ideas?

 

Thanks in advance.
