Dashboard Widgets won't update in Sandbox

[Impish]

Count me another satisfied customer of SuperDuper. I'm regularly running from a Sandbox, and occasionally doing a Smart Update of my MacHD, after which I always return to my Sandbox for daily use.

The only thing I've had trouble with is that I'm not able to update any widgets in my dashboard. That is, the installation of new versions appears to go smoothly, but when I'm done the old version is still there (and telling me an update is available).

I searched the SuperDuper help files for anything related to "widgets" but it returned no results.

Has anyone else experienced this? Is there something about widgets that prevent them from installing in a Sandbox system? Any ideas what to do about it?

Thanks!
