Better response but still ultimately crashes with same error: I do however get a notification indicting: "The save file operation failed." "The save file operation failed to connect to the open and save panel service." This is followed in the debugger console output with exactly the same output as shown in previous message. However the behavior is slightly different. There is a pause before the rainbow wheel indicates busy and as noted I do get the notification. I do appreciate the assistance and am grateful for any additional information or actions you could suggest. This is very strange to me. Oh I tried rewriting this in Objective-c and get a similar runtime failure. Very strange. ClsrkW
