I have disabled Preview Window (sensitive = false) thrue the "dialog-flipbook" action (yes it's the call the preview window smileys/2.png until the Preview Option is called (and the preview window created.)

Then, the action is always enabled (the preview window is only hided on close_event, never closed)

Possible improvement, let Preview Window action always sensitive and call Preview Option the first time.
