I have gone through countless editors to find something that will fit most of my needs and wxMEdit is a real standout amongst the crowd. Windows 8.1 after unzipping the download a very good readme file explain everything necessary to use the editor. My job is to do quality control for software programmers. It is demanding an a versatile job. Having a versatile editor helps a lot. I was able to easily open up an HL7 message and had all the right formatting required. Only one suggestion which would be some settings could be moved to the options sections instead from a drop down menu. This would only pertain to the view section. Convenience is great but some items once you set it you can forget it. Moving them to the options will allow for toggling on or off functions that you may want to do at times depending upon your workflow. Good Job.
