A box with an email address from a recent contact appears in the top middle of the screen over all open windows. It may be a person recently emailed. Is this a bug or a virus? I cannot remove the box but it goes away if I restart only to return later. This is a 27 inch iMac intel about 5 years old OS 10.10.2
iMac, OS X Yosemite (10.10.2)
Does it go away when you quit Mail?

Yes, it did, thank you. StI'll seems like a bug in the mail program. The address in the most recent box was the address of someone who recently sent a message, but the mail program had been running for a few days with many messages coming in before the box appeared.
I get the same thing. If I hover over a To or From field I'll get that sometimes. I haven't figured out exactly what I do to get it to pop up and remain. It's intermittent as you've learned.
Report it to Apple via http://www.apple.com/feedback/macosx.html. The only workaround at this time is to close and reopen Mail.
It won't hurt to reboot occasionally to clear out temp and cache files.
Been getting the same issue quite often...very annoying! (funny thing tried to post pic with the name 'apple error' which kept getting blocked...had to change it to 'apple screen pic' to make it load...very funny!!)
