The casino is doing the Win 7 upgrade thing at the moment, and when they ran out client side software, they discovered they cannot print. So I load it up on win 7, sure enough when you hit the print button, it no longer shows the print dialog box.
And what sort of muppets do a production rollout without testing it first ?
Testing print functionality prior to a rollout seems to be a bit of a no-brainer in the scenario you propose !
