No, that’s not true. Menu tracking runs on the main thread and does block other event handling on the main thread for the app that owns the menus. This is exactly the same as any other modal event tracking, such as pushing on a button, which also blocks other event processing on the main thread. However, there are the usual ways around this: - an event loop timer (using NSEventTrackingRunLoopMode) - using a separate thread, dispatch queue, etc. - using a separate process if necessary -eric _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
