After 4 or 5 tries I got the second account to load, and was able to move email to the second account, VERY HELPFUL CAPABILITY.

I haven't had the sending & saving problem lately so close out this request for help.

I just entered info for a second account but TB used info from 1st account. Last week it had trouble sending emails and saving a draft and then 160+ drafts of old sent emails appeared in Drafts (many were duplicates of same sent mail but with different timestamps).
