I put a NSLog () in the setFrameSize: override and it's only being 
called once, so that wouldn't explain it.  The description dump of the 
array each time through the resizeDayView method shows that it is in 
fact switching the first and last item in the array:

  <DayView: 0x13ba80>,    <----------------  this is the original 
item zero
    <DayView: 0x13dab0>,
    <DayView: 0x13dce0>,
  ........  37 more subView items ...
    <DayView: 0x147650>,
    <DayView: 0x147a60>  <----------------  this is the original 
last item 41


As the window continues its resize, the description dump shows it 
alternates to this:


    <DayView: 0x147a60>,  <----------------  this is the original 
item 41
    <DayView: 0x13dab0>,
    <DayView: 0x13dce0>,
........  37 more subView items ...
    <DayView: 0x147650>,
    <DayView: 0x13ba80>  <----------------  this is the original item 
zero, now at the end of the array


This happens every other time through the resizeDayView method. 
Strange huh?

Next, I'll try getting rid of NSEnumerator as you suggest.  For the 
life of me I can't see why the array is being switched.


Thanks
