That's right and why I stuck with it when it was integrated. I originally started to use it because it was small and fast compared with the major offerings. I still have back-ups from those days if you want bona fides. It's interesting that people wouldn't understand;
1 program that does everything = easy
2 programs that have to be updated, configured and accessed separately = annoying
All-in-one is a real point of market differentiation and I'm saying this because I've loved the program until this change.
I think that chrome has an add-on for the off-line browsing of mail. I'm off to check it out.
