One huge frustration is the fact that no matter what your reason for deciding to close the prescription writer after you have entered or changed something, it closes completely. Given the increased use of EPCS, there are many more times where after I enter something, I need to close that screen but keep the window open, ie. go back to where you can enter more medications or choose go to NewCrop screens. This is beyond annoying. Simply adding another button such as Go Back go Return to eRx window, could help tremendously.
