Subject: Ruby Tk and DRb

Hello @ all!

I wrote a little test code using RubyTk and DRb. But somehow I get 
strange errors:


(druby://localhost:9000) /usr/lib/ruby/1.8/tk.rb:2020:in `__invoke': 
can't invoke "wm" command:  application has been destroyed 
(RuntimeError) (DRb::DRbRemoteError)
        from (druby://localhost:9000) /usr/lib/ruby/1.8/tk.rb:2020:in 
`_invoke'
        from (druby://localhost:9000) /usr/lib/ruby/1.8/tk.rb:1549:in 
`_ip_invoke_core'
        from (druby://localhost:9000) /usr/lib/ruby/1.8/tk.rb:1583:in 
`_tk_call_core'
        from (druby://localhost:9000) /usr/lib/ruby/1.8/tk.rb:1607:in 
`tk_call'
        from (druby://localhost:9000) /usr/lib/ruby/1.8/tk/wm.rb:271:in 
`title'
        from client.rb:7



I don't know why and I hope somebody can help me with this code! Here it 
is:


--> SERVER.rb:

    require "drb"
    require "tk"

    class Test
      def startup
        root = TkRoot.new('title'=>"Hallo", 'geometry'=>"200x200")
      end
    end

    test = Test.new
    test.startup

    DRb.start_service('druby://localhost:9000', test)
    Tk.mainloop
    DRb.thread.join

--------------------------------------------------------------------------------


--> CLIENT.rb:

    require "drb"
    require "tk"

    DRb.start_service()
    obj = DRbObject.new(nil, 'druby://localhost:9000')

    root = obj.startup

    Tk.mainloop
