I am just using actions.
Now i get the whole picture :-)
Well, the least effort solution at this point is to just call the
method manually at startup. (and study bindings in the near future!)
Thanks,

You're not writing whether you're using bindings or just actions.
Bindings should automatically sync up your instance variable with
the matrix *if* you've set this up correctly. If it doesn't, it's a
bug.
If you're using actions, the cause is that the action is only sent
when the button changes. Target-action expects you to sync up the
controls and your data storage yourself at startup. One way to do
this would be to just manually call your action method at startup
so your code runs once and picks up the state of the buttons.
Typically, it's not the radio buttons that hold state information
(they only keep a copy cached for faster display), but a document
or NSUserDefaults, which is why you need to write this code. AppKit
can't know where the data comes from if you don't use bindings.
