Placing a button inside a button

Hey all!

I have a bar in a flash file that I want to change colour when a user hovers over it - so, it will be a ‘button’ symbol (correct?) - and on this same bar, I need to place two additional button symbols that appear when the bar is in it’s ‘over’ state - they both need to be ‘buttons’ as well (I believe), as they will be text, and become bold when a user then hovers over either of the links (in their respective button symbol’s ‘over’ state).

When I do this, whenever I hover over the bar, the bar flickers like mad, and the links don’t work…

Any advice, hugely appreciated!

Many thanks!

Jon
