I see the behavior, and one thing that immediately comes to mind is that 
you are using Control-Shift- as the accelerator and 
Control-Shift-Key-Greater as the binding: those are two different 
accelerators. In my apps I set accelerators such as Control-P and then 
bind all Control-P. I wonder if the control-shift is inadvertently 
causing the event to fire twice. Any reason for the mismatch between 
accelerators?
