I tested your code and I see what you mean. Perhaps you've found a Cocoa bug
(so you might like to report it). If you delete the setDirectory: call,
though, the problem goes away. It isn't needed anyway: Cocoa is already
implementing the logic you want (the second time, the panel opens to the
correct directory). m.
