Re: NSUserDefaults

Thanks for the reply. I realize now, I was expecting the wrong behavior. 
The bit about not writing anything to a permanent domain was right.  I've
now got it figured to actually set defaults later in the code and it works.
But I've not figured out how to store a default color. placing a NSColor
directly in a defaults object seems to ruin .GNUstepDefaults.  Is there a
way to do this other than getting the RGB components and storing them as
strings?

Thanks for the help

Rob

PS I've got about 5 or 6 copies of most messaages on
GNUstep-Apps,Bug,Discuss, and help. Is everyone else having this problem?
