Dru - too soon to tell - have had some Rx bugaboos today due to the NewCrop outage, and some general slowness which is probably related to this. For the most part, no major difference in functionality that I can tell.
PS - I was contacted by support and was told that the message disappearing when toggling between screens is the correct behavior. They are not sure why most of my office has not had this until the upgrade.
As a workaround, we have found the "Refill" button will call up the current med list for the front office staff, when patients call for refills to confirm their doses.
