Menu bar disappears, but I know it's there!

Hiya,

I am loading levels into a main swf, these levels load via a Menu bar built into my main movie… how do I keep the menu bar from disappearing as the other layers load into the main? I know it’s underneath my other levels cuz I get a mouseover on the buttons, I just can’t see the menu bar…

Any snippet of code to make this work would be awesome!

Peaceout.
