Box with unicode characters before the welcome...

[HelmutBlack]

Hi all,

I don't know what I did to arrive with this problem, but when I log on now, before the welcome screen and log in names, I'm greeted with a text box and an ok button on it.  I believe the characters on the title bar and inside the box are unicode characters.  You have to click ok, and then you can get to the users screen.  I don't know how to get rid of this.  Any ideas?

Thanks!
