   I am using the control definition function to provide my own control.
In the Drag routine, I track the indicator with no problem, but when it
comes time to reset the value of the control, SetCtlVal blows up (the
Mac crashes).  I can get get the value without problem, and can set the
value by dereferencing the control handle and jamming the new value into
the control record, and I can even call the Draw routine, but I can't 
seem to keep SetCtlVal from bombing. This is all happening in a modal 
dialog.  Any clues?

Thanks,
