If the customer is competent, you could check for memory leaks by
having the customer set a amall fixed size for the swap file,
rebooting, setting Win95 to manage swap, rebooting and have him
watch the size of the swap file.
Don't forget, Win95's TCP/IP stack sucks so bad it could suck the
World Trade Towers through a garden hose. We've managed to train
most of our users that when they start seeing bad net
performance, `no DNS entry' response for known good sites, can't
log on, etc., to reboot and try again before calling for tech
support. Most of the time the reboot solves their problem. He
may just have to reboot periodically, (that shouldn't be a
foreign concept to a Windows user :}) or run a real OS.
