When did 3.7 come out? I might have had the same experience. I think I have been using 3.5 with success, but I cannot remember exactly. I may have not used 3.7 for coding (as I had a couple of months break).
I will have to check, but apparently I have been using 3.5 with success, then. I will give 3.7 a try later, I hope it is really not that much worse, or is it? :(
