As it has for years, Norton Utilities does an automatic scan just about every day. It always says it found something, so I say "repair" and it does its' thing. While doing so, a dialog box says "Creating Restore Point". Once it finishes, I close the window and go about my business. Now, for the past 3 or 4 days, when it gets to "Creating Restore Point", it gets about half done and then freezes. I can't close the window or the program. I have to go to Task Manager to shut it down. Any thoughts about why this is happening?
