No, Intuition does not manage mutual exclusion of gadgets [correct me if
I am wrong JimM!].  Refer to pp. 59-60 of the V1.2 Enhancer Manual for
a description of how you can do it yourself.  In brief, though, you
RemoveGadget(), set or clear (as appropriate) the gadgets SELECTED flag,
AddGadget() it back, and then RefreshGList (or equivalent).

Ack!  Believe me, you *don't* wanna know what Preferences is doing...
