I clone my main disk to a USB drive once a week (3:30 am Mondays) and noticed the following messages in the Console log:

| 03:30:31 AM | Error | LOGGED EXCEPTION: NSAccessibilityException, reason: Attempt to re-add same observer of "AXWindowCreated" on element: <NSApplication: 0x316b40>, userInfo: {NSAccessibilityErrorCodeExceptionInfo = -25200; }
| 03:30:32 AM | Error | LOGGED EXCEPTION: NSAccessibilityException, reason: Attempt to re-add same observer of "AXWindowCreated" on element: <NSApplication: 0x316b40>, userInfo: {NSAccessibilityErrorCodeExceptionInfo = -25200; }

Is this anything to worry about?

I'm using SuperDuper 2.1.4 on a G5 dual 1.8 MHz running Mac OSX 10.4.9.
