Thanks, Maria - did this yesterday and it solved the problem. I really appreciate your help.
I did have something going on today, which may be related to the Yahoo problem. When I turned my computer on this morning, Incredimail didn't automatically go in to pick up my emails. It also doesn't do this when I switch identities, as it normally does. I have it set to check for new mail when it opens and when I switch identifies, and then every 5 minutes. Is this something else to do with Yahoo, or is there a setting I may be missing? If I ask it to receive all mail, it does - and after that, it appears to occasionally automatically check for new emails - but never when I switch accounts or when I first open Incredimail. Perhaps this is not the proper place to discuss this - if so, I apologize. Thought it may still be part of the Yahoo situation.
Again, thank you for all of your help! You are greatly appreciated!
