I have these three computers which all go through the same wired router/internet connection/network:
Dell desktop computer running Vista
Dell desktop computer running XP
Gateway laptop computer running Vista
Trying to change lineups with the first two computers is a nightmare. It always hangs, although it often will change the lineup. It's worse in my 1969 league which uses the old-style lineup interface. There lineup changes usually fail.
Fortunately for my sanity, I have no problems changing lineups on my laptop computer. It works fine networked at home and on the road.
I usually use Firefox, but using IE7 did not help. Certainly it's just a setting somewhere I have to change. Any ideas?
