Desktop Icons Rearrange After Startup

Hi, I'm having some trouble with WinME. For 4 years, no issues. My desktop
icons 'were' scattered (logically for me) all over my desktop. I boot up a
day or so ago and they automatically all lined up alphabetically starting
down the left side.

Updated and ran Norton 2004, Spy Bot-Search & Destroy and Ad-Aware, no
issues or problems found.

I've been scouring the web looking for assistance. Most people suggest
deleting the shelliconcache hidden file in the Windows directory. Did that
and rebooted, they still lined up. Rearrange them the way I wanted, rebooted,
and they still lined up.

So I tried adding the Max Cached Icon registy value as many people suggest,
set it to 2000 and went thru same process. Icons still lined up.

Any other solutions I can try? For such a 'simple' problem, it's rather
frustrating to try and resolve this one. Thanks in advance!
