Here’s a tech support session from a friend of mine trying to log into his bank account.
Web Customer: I’m trying to log in to my online account but the system is telling me that a session already exists. Can you cancel that session manually or do I have to wait for it to timeout?
Customer Support: You must close all browsers, wait about 10 seconds, then start a fresh browser session.
Web Customer: I think I did that and it didn’t work. If that’s the case, what’s the next step?
Customer Support: I would clean off cookies and temporary internet files, then reboot.
Geez…I know I’ve been away from UI stuff for a while, but I didn’t know web apps had changed THAT much.
