I don't actually mind OE6,,,, I get on well with it,,,, mind you, I said that about IE6 !
I tried to install IE 7 some time ago, but it kept failing, so I just left it. For some reason, today I decided to try again - with IE8. That installed as good as gold,,,, but I was expecting a newer OE as well.
If one is available - i'd better have it. If v6 is the latest, then so be it.
