The eRx issue in particular clearly affects useability of one of AC's most important functions. There are several posts daily about this problem. -- The slow display of the prescription writer affects my staff's workflow multiple times a day. Even with hardware acceleration off, sometimes it is necessary to kill the application in the Task Manager to restore responsiveness. -- Refill renewal window also fails to open, refresh or freezes one or more times daily. At the same moment, I can switch to Allscripts free "eRx NOW" program and send an eRx promptly. So it apparently is a problem with AC, not SureScripts.
