I'm having this same assenine problem all the time now. I also had this
problem 2 or 3 years ago on a different computer and hired a guy to fix it,
and he couldn't.

Anytime I try to switch identities now, it is totally non-responsive. It
just closes and ignores me like my kids do when I tell them to get dressed.
Oftem after awhile goes by, a window with the blue border on the top saying
Outlook Express pops up and it says: "Outlook Express could not be
started because another instance of it is still running on your computer.
Please log off of Windows, then restart Outlook Express. If the problem
persists, save your work, and then restart your computer."

WTH is this? I have done this 25 times already today and last night, and it
keeps happening. I have about 5 important email accounts here via Comcast and
I need to check them all, and now switching leads to be having to restart my
computer each time.

Any idea how I can fix this? I don't think it has anything to do with
spyware as I seem to be clean as I just did full runs. I sense, as this
happened a few years ago, that as my computer gets fuller, this happens.
