Hi Mimi
<
http://www.diigo.com/04kbe> for a highlighted view of <
http://www.bresink.de/osx/0TinkerTool/details.html>; the only feature of TinkerTool that's relevant to this topic is:
> Enable the developer mode of Dashboard
Approaches to enabling this mode are documented at <
http://www.macosxhints.com/> and elsewhere, but applications such as TinkerTool make it easy (without requiring use of the command line). Here for reference is a screen shot showing the General tab of TinkerTool:

Explanatory text is offered within TinkerTool :)
> Drag the widget while you are closing Dashboard.
Side notes:
1. I suspect that a widget cloned in this way (from iGoogle) functions only if Google credentials are available (from an unlocked keychain) before the widget is presented.
2. The Cocotron approach <
