So there are a couple of issues here:

1.) many browsers don't correctly manage z-indexing of iframes.
2.) the menu system doesn't currently do anything to trump this

As for the first point, what browser are you testing against? I know 
tha at least IE 6 and modern Mozilla's should handle z-indexing 
correctly for iframes and their content.

On the second point, we don't use an iframe for menu items since 
iframes tend to be egregiously expensive in terms of memory 
resources. If your app doesn't _really_ need an iframe, you might 
look into the NW content loading mechanism.

Otherwise, send me a link to the app and I'll see what I can do.

Regards.
