Larry,
I am on 11.5, sort of beta testing. It has been very good. There are improvements from my previous version. Seems more stable and I have been in close contact with AC tech support on things that we are finding. No big interruptions with this version. Less prescribing issues but still needs some tweaks. I will tell you that I feel Harris/AC is working hard to make the improvements we have all said need to be in place. Version 11.5 has been an upgrade from the last version I was on. I believe the last version I had upgraded to was 11.2.
My understanding is that Version 12 will include the 11.5 changes as well as any fixes they can get in there before the roll out. I am actually excited about Version 12 because 11.5 is a big improvement. General support for AC at Harris is at a high and I think they are making great progress.
Thanks Mark for posting about Version 12.
