I've fixed the problem. The Properties and the Preferences dialog callbacks only checked specifically for GTK_RESPONSE_HELP repose and were hiding the dialogs if else. I guess this issue appeared due to some changes in GTK+, so now some responses are also generated when you change control states on a dialog.
