If you have, then yeah it would be a good idea to see if it makes any diff. For some people, a various version won't/will make a difference. And since I've been on the forum I know it definitely can make a diff. Personally I use 4.0.4, though I'm going to try out the 4.1.4 beta bfore v.4.2 comes out. Strangely I just suggested the same thing to someone else not long ago but they ignored my advice. It can make a difference without a doubt.
