Even this beta version is working really awesome. I have also been able to trigger the error a couple of times, mainly when I did something dumb on the order page and then I think I clicked something else before it was able to respond to my first dumb move. (send an order that wasn't there, then add the order and send again all while the Wi-Fi is saying, "What, did you say something to me")
My point is the error is a minor glitch, the thing crashes, you click No on the error report (since it is the same error AC is already working on) you reboot AC and it asks if you were working on something you forgot to save and you say, "yes" and you get your chart back. No data lost, about a minute of time lost and then back to work.
The e-Prescribing is FANTASTIC. I never dreamed it would be this easy! Absolutely awesome.
