wxEuphoria -- Custom Dialog During Progress Bar Execution

I'm having a problem with trying to invoke a custom dialog while a progress
bar is active.  The dialog does not respond to input, and the app locks-up.
A canned dialog, like message_box, works fine though.  Any help, as always,
would be greatly appreciated.  Here is the offending code:

without     warning
with  trace

include     wxEuphoria.e
include     wxDialog.e
include     wxText.e
include     wxButton.e

atom void, vs, hs
constant
MainFrame         = create( wxFrame, {0, -1, "Main", 120, 120, 500, 400} ),
MainPanel               = create( wxPanel, {MainFrame}),
MainBtn                 = create( wxButton, {MainPanel, -1, "Start"}),
CustomDialog      = create( wxDialog, {MainPanel, -1, "Help, I'm stuck",
250, 250, 180, 100}),
CDlgCancelBtn     = create( wxButton, {CustomDialog, -1, "Cancel"})

procedure start_progress()
      integer     max_progress
      atom  load_progress, import_progress
      max_progress = 1000
      import_progress = 1
      load_progress = create( wxProgressDialog, {"Progress label",
"Progress", max_progress, MainPanel})
      for i = 1 to 1000 do
            void = progress_update( load_progress, i,"")
            if i = 500 then
                  void = show_modal(CustomDialog)
            end if
      end for
      end_modal( load_progress, 1 )
      if platform() = WIN32 then
            delete_instance( load_progress )
      end if
end procedure

procedure un_load_dialog( atom this, atom event_type, atom id, atom event )
      end_modal ( CustomDialog, -1 )
end procedure
set_event_handler(CDlgCancelBtn, -1, wxEVT_COMMAND_BUTTON_CLICKED,
routine_id( "un_load_dialog" ))
set_event_handler(CustomDialog, get_id(CustomDialog), wxEVT_CLOSE_WINDOW,
routine_id( "un_load_dialog" ))

procedure click_button( atom this, atom event_type, atom id, atom event )
      start_progress()
end procedure
set_event_handler(MainBtn, -1, wxEVT_COMMAND_BUTTON_CLICKED, routine_id(
"click_button" ))

wxMain( MainFrame )
