ToggleGroup explicit management

[Mark Fortner]

I assume that if you add them one at a time, you don't have any problems,
right?  If not, that would lead me to suspect that it's having problems
descriminating between instances of the RadioMenuItem -- perhaps hashcode
is improperly overridden.  I use ToggleGroups with ToggleButtons all the
time without any problems.

Cheers,

Mark
