I hope someone can advise me concerning this problem. I have an IBM ThinkPad X41. I have enabled Fast User Switching but when given the option the logoff or switch user, I choose switch user and I return to the welcome screen, and when entering the password for the intended user I get a temporary "blue sceen of death" which passes too quickly to read/analyze. The machine then reboots. I have contacted Lenovo concerning this issue and there answer is "yep, that's a known issue". No solution! Great customer support.
Can anyone advise?
