OK, I gave up on fixes and reinstalled frm original disk, Win XP Home Ed.
Tho't I did it right this time. Installed drivers from Drivers Disk, but not
Apps yet.

Installed SP2 frm disk. Defrag'd. My Comp properties reads: NTFS, WIN XP,
Ver 2002, Sv Pk 2, 55277-OEM-0011903-00105".

Downloaded both AVG and IE7 programs; saved in My Downloads, but....when
went to upload get msg on both "...not a WIN32 app"! Hey, I had both running
before I did the clean install!!!
