The double popup sounds like it could be from the query slide which is used in the last update ( if memory serves its called sexy popup) which isnt actually done by me so i cant say.
The google login sounds like a setup / config error ( mismatch with the redirect URL ).
As for Twitter ive already coded a login function but i didnt supply it as its not really adequate for a shop. Twitter does not supply Email address as a means of proving credentials only first and last name.
As its possible ( although unlikely ) that more than one shop customer can have the same first and last name , it could create some problems.
However as Email addresses are unique - testing credentials against first / last name AND Email ( which my contribution does) proves 100% that the customer is who he/she says he is.
