How to remove default menu items in a Mac Air application

Hi Everybody,

I have a Air application built in Flash Builder which runs on Windows as well as in Mac.

My application has it's own menu bar. In windows it's OK.

But in Mac above my app's menu bar there is a default Mac app menu bar with four items(App Name, File, Edit, Windows), which is totally unnecessary.

I want to remove the Mac's default app menu bar.

Please help.

Thanks in advance,

Jameel
