What is the suggested user interface when creating modal dialogs for documents that have be movable? For our application (think of it as a drawing program), the user sometimes NEEDS to be able to view the document under the modal dialog. We can not use sheets, because they cover up the document window itself. We can not do Inspectors, since the operations are intensely modal. We could make the dialog box application modal (ie. one at any given time), but our client has really requested document modal, since they are often working with more then one document at the same time. I know how to write and invoke the code to make any given window modal to another, but I am more concerned about the user interface of this. Is there any suggested way to do this? Something to clue the user to what is going on?

I don't think you can do it with off-the-shelf components.

An idea, I don't know how difficult: In the document window, under the title bar, animate in an additional NSView containing the modal information. It would push the document content down. Institute a runloop mode (or possibly just a document flag for your UI validation to inspect) that enables viewing the document, but not changing its state.
