Bummer, that didn't work.
I don't think its the bar thats the problem .. its the buttons not appearing until it is reloaded.
So maybe something to do with when the buttons are created and applied to the bar .. more investigation I guess
Ah, order matters doesn't it .. switched them round like you have and testing again.
Nope, same problem. It must be how nUI builds the buttons and the bars.
Oops, forgot the index change, nope that didn't work either ..
However, I did notice that although the button didn't change the key for the button worked. So must be an assignment of the button to the bar problem with nUI.
