[QUOTE=When they entered their account number and password, the "welcome" block in the upper righthand corner read "null, null, null".

- Is anyone else experiencing this problem?

Yes, for some weeks now it happens to me as well. I go around it by going through the menu on the left in stead. When the miles summary doesn't show in the top right hand corner, I click 'frequent flyers' on the left. And go to account overview that way. Worked every time for me.
