We've installed Notes as our email system on over 20 Windows 98 PCs. We have trouble with about half our systems slowing down throughout the day, until finally the mouse pointer begins to move in slow steps or not at all. Some systems do not have any performance problems at all while identical hardware (GP6-450) will slow down throught the course of the day. Clock actually starts losing time, today mine lost 10 minutes, some weekends I leave it on and it's lost 45 minutes by Monday. We thought we might have identified the problem as an active qnc.exe file, but apparently not. Any other ideas?
