Best and worst customer I've had: A bank.
Great because they had so much money for projects.
Unbearable because everything needed to work in IE6.

IE6... Ewww. That's old!

For a sector that requires top security measurements this is just bad... especially that
1. IE6
2. Requires Windows XP
and both are no longer supported by Microsoft ...

My regrets, I know this story very well. And the best point is that I work for a security company...

Maybe it's the intranet apps that need ie6.
Consumer facing apps should be ok

at LEAST use firefox, come on people

@gitpush They were only allowed to use XP until like a year ago. Don't know if they got caught in the 'optional' upgrade to Windows 10.

@ParkCity There was a "hack" (they really called it that) in which they used Chrome from time to time. Wasn't allowed but they eventually rebelled.
