There are some bugs in Windows ME memory management that causes "issues" when its run on machines with "large amounts" of RAM. Microsoft documented this and you should read about such at http://support.microsoft.com No patch was supplied but a workaround to tell ME to keep itself to 512MB.
The defrag issue is noted in the Windows ME forum in a note I keep on the first page.
Here's an article about Windows ME memory -> http://aumha.org/win4/a/memmgmt.php
Why does my desktop computer (Windows Millennium ME)performance start up at only 45-50% when I have 896 MB of memory, even when I haven't logged onto the Internet?
Why does the defrag process stall on the c:drive? It can't get past 10% complete.
I ran spyware and I have current Norton Internet/Antivirus security.
Thanks for any help you can give me!
