Well, logically the request is modal, the user shouldn't perform any 
other actions until he inputs the data. Usually modal panels should be 
easy to do, so I guess I'm missing something here.

It looks you suggest more some kind of workaround? or is the "close" 
button incompatible with a modal panel? I tried some google-gu, but 
found nothing of use.

I also wonder about the differences between GS and Cocoa.
