Unless you are trying to access a shared resource that the current user doesn't have access to you shouldn't have to log in twice. So, you may have run into a program that steals your password or something. To see if this is true try typing in bogus information (Type in gibberish or random keys for a password) and see if the login screen goes away. The fake one *should* accept it, but the real one would say the password is wrong. Unfortunately though, some of these programs are more advanced and are acturally able to completely hide the real one, and just forward the information to see if it is correct or not. But, if both of these prompts only work when the right user/pass is put in, it *might* be legitimate... If not...

I'd suggest doing a virus scan / spy ware scan, making sure both programs have the most recent updates/definitions. Is this a Windows 9x machine, or is it NT/2K/XP? If it is NT/2000/XP you should find the option where you have to press CTRL+ALT+DEL to log in so that you can tell which one is a real login screen. (The real one show up after you press CTRL+ALT+DEL, not before you finish the entire combination also) As for a 9x (95/98) machine, there is no option like this. In either case, to get rid of this you will have to go through startup files and find out what doesn't belong, if the Virus/Adware scan doesn't find it.

Hopefully other AO Members can offer more insight to this since I'm going to be going on a road trip soon. Good luck.
