I just started testing/using 1PasswordX as part of the beta testing. First, I want to say that this is a great approach, the interface looks amazing, at this point I am starting with 1.7.0 so I guess many things have been iron out by now cause it works really well so far, with all the sites I have tried. The only thing I have experienced is that when clicking the icon to get the main screen and scroll up and down some menu items appear and disappear, I managed to capture the screen, see here below.
I have another comment about the Password generator screen, I think the recipe for how many special characters or number should be included, and I think I saw comments that it is in the Chrome extension alreadu in 1.8, so hoefully soon in FF as well.
