I have three users on my laptop, and haven't had a problem switching between them until recently.
The computer's trick is: Two out of the three users come up just fine, but the third person has their background, but no explorer, desktop, etc. I can pull up task manager and run programs from there, but again, no desktop to rely on. I'm guessing maybe it's an error initializing explorer????
I'm not computer-illiterate, but this one is unfamiliar. Thanks for any ideas or suggestions!
