Dear Ryu,

we've coded up our own example menu based on what you made for us - and thank you very much for that - we notice however that the resulting menu is nowhere to be seen on the frame.

When we did buttons we had to associate them with a frame - and I note that there seems to be no association to a frame in the code you wrote for us - so we never see a menu - is 
this what is to be expceted ?

thanks 
Farrukh
