But if I pick up an object and drag it to the edge of your document window, do I expect further movement to scroll the document window, or to switch to an out-of-application drag? --Kyle Sluder _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
