hide and show on OSX problem

[Krzysztof B. Wicher]

Hi,

I already posted this two weeks ago but it probably has not got to _why.

There is a bug in hide/show for slots, causing the strange behavior of the
nested slots, at least on osx. When running:

Shoes.app do
 @t1=stack :width=>250, :height=>250 do
         background green
    @i1=flow :width=>200, :height=>200 do
      background red
      para "\n\nOj Oj"
      @r1=button "kkk"
      @r1.move(40,100)
    end
    button "toggle inside" do
      @i1.toggle
    end
end
    button "toggle outside" do
      @t1.toggle
    end
end

- "toggle inside" - toggles correctly the red stack, and the contained "kkk"
button and "Oj Oj" para
-"toggle outside" - toggles correctly the green flow and the "toggle inside"
button and  "kkk" button BUT the red stack is still visible as well as "Oj
Oj" para.

Thanks
