E-mail Error when checking manually?

[lizardbrains]

Hi, all! What a fabulous resource you all are! I've been enjoying reading through the threads here, and learning so much (even if most of it is above my head).

I got my Mogul less than a month ago. I set up the e-mail account (a yahoo one) and it's pushing very well, and doing everything I could ask it to do! Very cool. BUT when I manually hit "Send/Receive" on the Menu, it gives me an error message asking me to type in my password. If I enter my password, it says it's wrong. If I don't enter anything, it says it's wrong. So I've just learned to skip the error and just say "okay, nevermind". KWIM? This also happens periodically as I'm going about my business on the phone... the box will come up asking me to enter my password. I just skip it, since it never accepts my password as correct when I do answer it. And even though I skip the error message... it still checks my e-mail just fine (eventually, a few minutes later, but not at the moment that it gives me the message).

It's annoying, but tolerable. Am I the only one having this problem?
