(sorry for the repost, I forgot to change the subject line before)

I'm struggling and maybe tired, but how do you set the state of and 
NSMatrix with radio buttons and NSPopUpButton ?
Does it go in windowDidLoad or should it be in awakeFromNIB ?
This is in a Preference window for my app.
I'm having a hard time figuring out how to get it to set state to 
reflect the userDefaults.
No trouble with changing the defaults after a selection, just 
reflecting the current defaults on load of the window.
What methods am I missing?
For the popup, I have tried selectItemWithTitle, selectItemWithTag, 
etc...
For the radio button matrix, I am totally lost and I don't understand 
how to set the state of it. Does the matrix need IBOutlets for each 
cell too?
