This happens every time I start Evolution and I was in the Mail view the last time I quit.  "Enter Password" dialogs pop up for my various email accounts, and then they lose focus in a few seconds as the rest of the application starts.  I'm well used to this behavior by now, but it's still an annoyance.

And to a newbie, it's a security risk if they start to type their password in the dialog and the focus suddenly goes somewhere else.  I think it would be much better if the password dialogs kept their focus.
