Apache on Win98 original, Windows Explorer freezes

Ever since I upgraded from Apache 1.3.26 to 1.3.27 (uninstalled the
old one and downloaded the MSI file for the new one), Windows Explorer
has been having issues. I read a post in the NG from 1999 where
someone was having the exact same problem, but there were few
responses. I'm hoping that someone else has come across this by now!

Whether I have Apache running or not, ever since I installed it
Windows Explorer freezes up on me for no apparent reason. In any
folder, when I try to create a new folder, copy-and-paste, or
whatever, it stops responding completely. Sometimes it will respond
after about 45 seconds, but sometimes it just doesn't come back at
all.

When I Ctrl-Alt-Del, I don't have anything major running in the
background; my digital camera card reader, Explorer, and a file that
my modem is requiring. All of this was the same as when I had 1.3.26.
I had read that changing the HostNameLookup in httpd.conf would cause
a similar problem, but I never changed that since the server is just
here for occassional testing.

Has anyone else seen this problem? If so, any ideas on how to fix it?
Rebooting has no effect, and my CPU resources (according to
Win98>Performance) is at about 85%.

TIA,

Mike
