It's a bug in 7.7 and they say they work on a fix. I think it was fixed in beta 7.7.1.It's pretty annoying to always click on "not now" when logging into a site. Guess it's back to lastpass then? :/
Have the same issue and it drives me nuts with the 7.7 release. In general 7.7 is very buggy I hope this is not a sign of 1PW going downhill. Stability over features.
