Can you turn off LCD or VF-2 when VF-2 is plugged-in?

Hi,

I just got the VF-2 and popped it onto my EP-L1. I have the Record button mapped to turn off the LCD display. This functions just fine when the VF-2 is not plugged-in, but when I plug in the VF-2 the Record button doesn't turn off the LCD or VF-2. I'd expect the Record function button to turn off whichever is active to save a little battery life. Am I missing something?

Thanks!
Nikolaus
