[QUOTE=signals;5714]Use of older versions causes support problems. You never know if the older version is partly responsible for the problem. That being said I have to confess to having my favorite v4, v5 and the latest version installed and available with just a click. In general the newer ones run faster, work better and are more stable.[/QUOTE]
Ditto on all that pard.
I still have v4, v5, and the most recent release installed.
My all time favorite is still v.4.1.2.0
You'd have to pry this one from my cold, dead hands...:eek::D
(I don't recall going back to v2.x or v3.x in years)
