Hi, 
I have the following browser:

| browser |
browser := GLMTabulator new.
browser
    row: [ :r | r column: #one; column: #two];
  row: #three.
browser transmit to: #one; andShow: [:a | 
a title: 'One'.
a list display: [ #('Something 1' 'Something 2' 'Something 3' 'Something 4')];
selectionAct: [:list | 
(list pane port: #customSelection) value: 1 ] 
entitled:  'Open new panel'
].
browser transmit from: #one; to: #two; andShow: [:a | 
a title: 'Two'.
a list
display: [ #('A' 'B' 'C' 'D') ]
].
browser transmit from: #two; to: #three; andShow: [:a | 
a title: 'Information'.
a text display:[ :x | 'Information related to ',x asString ] .
].
browser transmit to: #three; from: #one port:#customSelection;andShow: [:a | 
a title: 'Three'.
a list
display: [#('A' 'B' 'C' 'D')]
].
browser openOn: 1.

When a value of the list of the pane "two" is selected a new pane is open in #three. Also, when the action of the pop-up menu of the pane #one is selected, a new pane is open in #three. My problem is that the new pane opened after clicking in the pop-up menu is only shown the first time that it is called. That is, if I click in the menu, then I click in an element of the pane #two and finally I click again in the menu action the pane #three is not shown this time. I'm doing something wrong? I can't understand why this happens.
Thanks!
 Cheers,
   Santiago
