AC support logged on remotely to address speed issues. They adjusted the hardware accelleration and told us to adjust it on all clients. They said get more memory for the server, our is just a desktop running XP pro with 3GB RAM.
I never spoke to them and wasn't there at the time, so I might have missed something. I wish they'd followup with an email summarizing what they know about the problem and their recommended fixes. But from what I saw it's disabling hardware acceleration and beefing up the server.
We've gone 1.5 days since the changes and reports are the speed is bad but tolerable. I was watching the doctor running AC and I see how it slows her down even at 1-2 seconds for screen updates.
I'm $450 poorer, but the response when i went to prescibe today on the new, 64 bit win7 laptop was instantaneous.
I ordered one WIN7 laptop for us to try. It it totally fixes the problem I will try updating some other machine to WIN7. That will be a good test of new hardware and new OS vs. new OS only. Ideally we don't have to replace all our machines, we have 5 laptops and 4 desktops and 1 server.
