dartman51, I also find that the program sometimes crashes when I start to do IND scratches, but for me after restarting the program it very soon starts working completely fine again. Just takes me a few more seconds to do IND.
But I am using Bris data files so maybe it's less crashy for me at IND than the jcp data files.
I've used HDST quite a bit and I really like the interface, how much time/hassle it saves me, and how it works in every way. I'm grateful to Headhawg for providing such a useful tool to the handicapping community.
Happy Preakness everyone!
