I have noticed for months now that after doing a reboot of my "main" computer , where the AC database is, all the other computers running AC run very fast and smooth; then after about 3-5 days, some sort of "hiccup" occurs whereby everything within AC gets very slooowwww.... all I have to do is to reboot the "main" computer, then everything goes back to being fast again, at least for another 3-5 days. The main computer is a Dell PC less than a year old, and stays on all the time. I don't turn the "main" computer off at night in case I need to access remotely, and also because of the online backup scheduled for 1:00 AM. I have been repeating this cycle for months now. Does anyone else encounter this?? If so, is there a way to remedy it? Thanks.
