Thanks for responding, Micha.

I searched and found that function in controls.pp.  Placing breakpoints at the 
beginning of the method(s) indicates that it is not being called, although I'm 
not sure where it should be called.

I'm testing a new control which I need to represent a button in a touch screen 
based application and the conditions for this to happen are very good in that 
environment.  It would be very confusing to a user (and result in many phone 
calls) for a user to press on a button, have its color change and then not 
change back when they moved off of it.
