I expect you should have initialized your OSX.NSRect thus :
			matrixFrame =3D NSRect.alloc.init

I thought so too. I tried that first, but

	RBException_NoMethodError - undefined method `alloc' for=20
OSX::NSRect:Class (OSX::OCException)
	RBException_NoMethodError - undefined method `init' for=20
OSX::NSRect:Class (OSX::OCException)

Also, using NSRect.new, if I

	p matrixFrame

I see this in the log:

	#<OSX::NSRect:0x28aa7c @size=3D#<OSX::NSSize:0x28a874 =
@height=3D40.0,=20
@width=3D28.0>, @origin=3D#<OSX::NSPoint:0x28a888 @x=3D20.0, @y=3D20.0>>


Which is exactly what the NSRect frame looks like from a matrix built=20
in Interface Builder. So as far as I can tell, my matrixFrame is set up=20=

correctly. {shrug}

I haven't done all that much with ruby-cocoa lately, but as I recall,  
NSRect is a Ruby class, not an Objective-C class.  And I remember  
using #to_a to convert it to a format that Cocoa methods seemed to like.

Of course, I could be all wrong here.

That doesn't work here.  NSRect is a C struct, not an Objective C class,
so that the very least there is no init possible for it.
