I have E3 & find that good for me, i gave up with the compromise that AD had with windows 8, they didn't seem interested in a proper fix.
Kevin i know where your coming from but we are paying good money which should include windows 8.
I tried Autovista & found it frustrating when it timed out which i haven't had with E3.
If there is something you need & E3 hasn't got it, there is a link for tech support which so far they haven't let me down

Regards
