Thanks all for your help.
Carl, I'll try implementing your suggestion over the next 2 days. I'm not technically as astute as I was in the early days of WIN 95.
In any case, when I use AC at home, at night, the flow is much better with minimal shuddering. But, if at home during the day and the staff is also logged in, the problems are the same as when in the office.

Also, with 4 users, what do I need from a server if we return to in-house AC? My IT guy asked to find out if SQL is needed.
