Meche94,JaxMacFL and Brink,
Thanks guys, but unfortunately, neither of your suggestions worked; Brink, I actually went to a thread I believe you posted on how to modify the system registry to get Windows Sidebar functional again, but to no avail.
Any additional guidance to resolve this is greatly appreciated; I've since discovered that Protected Mode is off when in IE 7 and I've made several attempts to turn it on with no success either.
Henri,Unfortunately, no. I deleted those files then shut the computer down completely; after restarting and logging in, I waited several minutes to see if the side bar would appear but it hasn't happened.
