Does it connect to the internet? Yes.
Do web pages display in the window (not beside it, under it, to the left of it (etc))? Yes.
Do the web pages look a bit shonkier in IE7 than in IE6/Firefox (etc)? Yes.
Past test 3, I’m stuck as to what to suggest to my boss as to good things to check in IE7. Any help to the usual address (etc).
