Don’t know if this helps, but Aim stores my buddy icons under “Documents and SettingsAdministratorApplication DataAimbartcache1”. All the icons are stripped of their extensions, so the best way to open and view them is probably to drag and drop them into an Internet Explorer window. If you log into Windows with an account other than administrator on your pc, you should probably look for a folder with your login name under “Documents and Settings” then “Application DataAimbartcache1”. The buddy icons on my pc, other than being stripped of their extensions have long file names, example “1332AE8791FEB1EA16C7DD9647C937F1”. Hope this helps.
Oh, I’m also running Windows 2000 Pro, and AIM version 5.5.3598
