I don't know if this will help, but from an unrelated KB article I saw
(
http://support.microsoft.com/kb/930277), it looks like:
"Configuration information about the gadgets is stored in the Settings.ini
file in the following Windows Vista folder:
C:\Users\User Name\AppData\Local\Microsoft\Windows Sidebar"
From what I can see, each gadget has a "Section" in that ini file. I don't
know if you should 1) just delete the file entirely in the hope that Vista
will recreate a default, 2) delete extra sections, or 3) see if there's some
kind of "Number of Instances" in there that is set wrong.
