Hans, I know upgrade is easy, I've done that before ;) Believe it or not, my (yes, MY) problem is, that PC I use on daily basis is unable to write USB drives. Can read but cannot write. Unbelievable? :)? So firmware update means I gotta go grab some other PC. And that's the reason I'd prefer to know in advance.
No worries, just do your job and if I'm one version behind, that's no big deal.
