You're actually seeing the cursor in Finder (and other apps) when opening a menu that requires a significant amount of time to open or render (which the "Open…" menu item often does). Menus in OS X apps (both Carbon and Cocoa) are still implemented using the Carbon Menu Manager, which accesses this cursor via the Carbon API SetAnimatedThemeCursor. I don't believe there's currently any NSCursor API for accessing this cursor; a Radar would be appropriate. -eric _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
