Thanks for your input. I find that my office "main computer" to which I connect remotely is often so slow. When I reboot the Comcast modem and the router the speed returns to a usable level. Otherwise my typing is so much faster than the response on the other end that I might think about becoming a transcriber after I retire!
Perhaps I might try AC as an online app. My question in that circumstance is: can I continue to run AC in the office as a server/client arrangement and then use the online connection at home or elsewhere? Can my at home work be synced to the office server?
