Pop Up Window

[Juan Matías]

Hello everybody, this is my first message.

I'll made this simple reminder. I give it some minutes and a note. When the
time is ended a pop-up window alert me with the note I wrote.
In Windows the pop-up window rises over the others windows, that's fine!,
but in Linux this does not work, pop-up window kept below.
I need this alert window appear above(on top) all the windows that I have
opened.
How I can open a window on top level?

Shoes.app(:width => 250, :height => 180, :title => "Boomerang with a note.")
do |boom|
  background "#EFC"
  border "#BE8", :strokewidth => 6

  stack(:margin => 12) do
    flow do
      para "Write a note: " # ex. "Rapidshare downloading time wait"
      @note = edit_line
    end
    flow do
      para "Return in(minutes): "
      @time = edit_line
    end
    button "Attach and Throw!" do
      wait = @time.text.to_f * 60
      timer(wait) do
        alert "[EMAIL PROTECTED]"
      end
    end
  end
end


Sorry for my english
