When you right-click on the WindowsME desktop or inside a Windows Explorer box, you normally get 'New' as a sub-menu option on the popup menu - letting you crete a new folder, text document, word document etc. A couple of times I've noticed this isn't there on my system. Normally it is but twice now I've come to create a folder and been unable to, having to resort to doing it through a dos window! If the WindowsME menu bar at the top of an explorer box is meant to ahve a File->New option, that too is missing.

What could be causing this option to periodically be removed (not disabled, it just doesn't exist) and how might I fix it?
