A few days ago I discovered by chance that my PC has somehow folded my Local Settings in on themselves in a kind of recursive loop. If you go to Local Settings and expand the Application Data folder you find that Application Data contains a complete duplicate of Local Settings, including an Application Data folder, which in turn contains a complete duplicate of Local Settings, including an Application Data folder, which in turn ... and so on through 24 iterations. Ought I to be worried about this, and if so, what should I do about it?
