I don't question Quincey's experience with -[QTMovie frameImageAtTime:withAttributes:error:], which I haven't looked at. But I agree with Chris as to the NSEvent methods I describe in another post, and the similar methods in my own frameworks. In these cases, when the Cocoa object goes away, its CFType-derived counterpart also goes away. -- Bill Cheeseman - [EMAIL PROTECTED] Quechee Software, Quechee, Vermont, USA www.quecheesoftware.com PreFab Software - www.prefabsoftware.com _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
