I will say I really like the 6.0.9 Meaningful use wizard. Very well thought out. I was happy to see I hit >50% of the metrics without even trying.
However, there is no doubt a programming problem for the prescribing module. It works swiftly in 5.1.7 and drags to a crawl in 6.0.9 on XP machines. I suspect the only reason Win 7 machines work is the speed of the processor overcomes the faulty programming. I hope the programmers at Amazing Charts figure it out soon. I am not against upgrading to Win 7 if I need to, but I really don't think XP is the problem. Why would 5.1.7 work so well and fast and 6.0.9 tank - it's got to be an Amaz charts software issue.
