Anyone tell me how/why I've lost the capability to select the FMC from the FO FMC.  Is it restorable without a restart?

 

Recycle your views using the A button on your keyboard, then reduce the screen. You should then see it top left corner

No luck.  Doesn't appear to be related to screen size or position.  I can resize the pop up and not see it.

Are you stating that you cannot recycle your views using the A button?

 

Edit: I see that this is a double post and there is another suggestion and your reply there.
