Change the relevant line(s) to: 
        -command => [ sub { $mw->destroy(); ex2();} ],

presto change-o! $mw is destroyed and ex2's window is created.

With the current code, ex2() doesn't exit until its MainLoop is finished, so the second command (to destroy $mw) isn't executed until after ex2()'s window is closed.
