It seems like it depends on how the mouse click is detected within labview - on the desktop a property node of mouse information can be used to detect a button down action but this does not register on the vivotab unless a double tap occurs. I think I will try using an event structure and a mouse down event. This looks like it might work if I can figure out how to incorporate it into my existing program. Does anyone have any ideas why the property node button down wouldn't register?
Thank-you!
