 {{{
 framework 'ApplicationServices'
 framework 'Cocoa'

 class Tester
    def start
        @callback = Proc.new do |count, rects, userInfo|
              puts  "callback"
         end

         err = CGRegisterScreenRefreshCallback(@callback, nil)

    end

    def stop
         puts "stopping"
         CGUnregisterScreenRefreshCallback(@callback, nil)
    end
 end

 t = Tester.new
 t.start
 trap("INT") {
    t.stop
    #exit 0
 }
 NSApplication.sharedApplication.run
 }}}

 Using the above code, I can get screen refresh callbacks, but when I try
 to stop and unregister, I keep getting called back until I kill my
 terminal session. I wrote an equiv. ObjC test app and it works fine. I can
 post that if needed.

 Cheers,
