yes I think so I haven't tried it yet, I had to go out for a while but don't worry I will get around to it I think it will be better if I create my menu in a logical step to achieve the goal.  Then I can crack on with getting it to work with my menu item

thanks gironis

Well that certainly was quick Tim you are a true expert ... How do you do that?   but sorry I don't think I explained myself  as I should have done

heres my menu or at lease a simulation of it

THE MENUBAR:
---------------------------------------------------------------------------------------------------------------------
Game   |    Choose background  |  Sounds  |   Help
...................................................................................................................................................


THE TABS:
GAME
--------
Start
Single or multiplayer - Single player
                                - Multiplayer
quit


Choose Background
-----------------------
Default
Long grass
Yellow sand
Blue snake glass

Sounds = Checkboxes
--------------------------
Music on / off
Sound effects on /off


Help
-----

User instructions
About box

Does that make any sense ?  thanks !
