My email INBOX is SO weird!

I just checked my Control Panel, and MY time is set correctly, proper time zone, etc.

I sent someone an email; within about 15 minutes, she replied. Her message is timed 5 HOURS earlier!!!!

Now, if I could figure out how to "capture" this, I would go back to a younger age, lol! Meanwhile, any ideas what is happening with my IN box?

Oh, I do not use Outlook Express, I use the ISP's email, as I bounce between my laptop and my PC and I need to see email from either computer.

Thanks!
