If I may impose upon your, or anyone else's wisdom, once again, I noticed I am also have a similar problem with the "My Network Places" icon on the Desktop. In this case, if I revert to the default Windows XP icons, that particular icon changes to an IP package icon rather than the XP default icon. It will change, although with some hesitation and only after clicking "refresh" on the Desktop to the current icon of the IP package I'm using.
Anyone have a "fix" to resolve this one? Everything else is working as it should, thankfully. hehe
