Yep, it didn't want to play nice for me. Once I saw the only real difference was the look / style I decided it wasn't worth the hassle. If their were some new bells and whistles I may have proceeded further, but with most things for me it's a time vs. effort thing and I found that I had better things to do with my time then monkey around with 4.3.
From what I've read here, some get it to work fine and others don't.
