@Arne.
Thanks for your reply.
The new dialogs still don't work. as my first EDIT states...
They are translated but it seems that there is a mistake (or typo) from your side that does not show the Filter Ports Dialog box in Spanish.
In my EDIT2 I meant to say that I had made a mistake changing some values (which in my opinion should be translated) but I left them as they were before 'cuase they were freezing the Hosts tab.
Sorry if I was not so clear.
So, if you want to leave this dialog box untranslated, for me is just Ok... I just wanted to clarify.
Other than taht... ust go for it...
Kind Regards
