eRX is working fine. The screen redraw was an issue for us in v6 with the Prescription writer which we resolved by disabling hardware acceleration. Also, if you use the star printer, I'm not sure if they resolved the issues yet as we don't use it. There was a slow down after we upgrade to v6, but it's manageable. Our computers are 6-7 years old, with the exception of our server which is new.
