Does Cocoa have documentation that describes why this functionality is not supported? To try it out is simple, create a default application that uses Objective C in XCode, add a button that toggles the window into fullscreen and opens a modal save-as dialog at the same time. The fullscreen transition will half-complete but kick the application out of fullscreen instantly. Is this expected behavior? The test application is attached below.
Cocoa: Simultaneous fullscreen toggle & opening of modal dialog fails
The reason why I'm asking this is because real world applications use Cocoa and seem to have pretty severe issues because of this and I am just looking for confirmation from 3rd party, or someone that this indeed is an issue (or simply just the intended behavior, because it can't support it or something like that).
