Our app already uses asynchronous document opening. I simply whacked in a sleep(5) call to make sure that opening documents takes a long time. With that in place: 1. Bring up the Open Panel (File > Open, no custom code here) 2. Select a document 3. Click Open 4. The panel disappears shortly after 5. After a delay, the document appears Thus I conclude that if you are seeing the open panel hang around, you're likely doing something wrong to block the main thread. _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
