Losing Focus Whilst Switching Panels

[weejohn]

I've been working on NGUI for 3 days straight now...and I'm now bald from pulling out my hair 
I'm trying to switch between panels...which only use the UIButtonKeys, not the mouse for input....and everytime i go from menu A to Menu B, the first button is in focus enabling me to navigate the menu, however switch back from B to A there is no focused button so I cannot navigate. I'm probably missing something very simple///please help, the more I try to fix it the worse I make it!

UIButtonKeys has fields for which object gets selection when you use keys: Select on Click, Select on Up, etc. Did you set these? On Click one is what determines what object will get selection when you hit Enter (or A on the controller).
