Mel, I wish I had a crystal ball to see what is going to happen with DP 9. I had one case with reporting that DP 9 resolved, but this is a very small drop in a very big bucket, but, given the history of recent releases, I would advise that if an upgrade to DP 9 is contemplated, wait at least until the first set fo patches come out
My advice to you is to upgrade to DP 7, install the patch bundle that will bring you up to 7.03, and get the latest individual patches installed. it uses the same IDB as 6.2, and this is where a lot of the problems with DP 8 are happening. This will give you another year of a supported, stable version
