John said "Are there any bugs so serious that you would recommend a re-install of UFT2.x in a separate directory?"
I consider some of the remaining bugs serious I DON'T like my son's picture to be a gravestone!), but these were also in the 2.x series (except for the tombstone calculator thing).Bottom line: 3.1 is good enough as it appears to be now to be the only version installed (except for people like me; I like to keep the others so I can help people who never upgraded to 3.x).
Of course that assumes there are no NEW bugs in 3.1 that we haven't discovered yet.
