Hi,

 I'm having a bizarre problem with Ruby/Tk.  I'm running OS X 10.4 with
the standard ruby:

ruby 1.8.2 (2004-12-25) [powerpc-darwin8.0]

 The code below is the simplest code that reproduces the problem.
Namely, when run, I see my window and scrollbar flicker rapidly,
apparently between two different sizes.

----
require 'tk'

top = TkRoot.new
f = TkFrame.new(top)
sb = TkScrollbar.new(f,'orient'=>'horizontal')
sb.pack('side'=>'bottom')
f.pack
Tk.mainloop
--

All of this is required.  It works fine:
  * without the intermediate frame, f
  * without orient=>horizontal
  * without side=>bottom

Any help would be much appreciated.  Please e-mail any replies to me at
calfeld / math.utah.edu as I do not read this group regularly.

Thank you,
  Chris
