Thanks to all your responses. Sorry I didn't mention this, I am using Windows XP.
It seems to me that I should stick to the 1.5.5 and not move up until we get the final OK to do so. I don't want to mess things up. I was surprised from James' mail. How is it possible to have a 1.6 and a future 1.5.7 side by side?
