Answer 1

As a rule, you shouldn't really be running modal sessions inside modal sessions. Not only is it really bad UI, it's quite complex to get right.

Have a look at Apple's modal session documentation for detailed information on modal sessions: http://developer.apple.com/documentation/Cocoa/Conceptual/WinPanel/Concepts/UsingModalWindows.html
