Hi Roy,

I had the same problem but i think i have worked it out.

Go to http://www.snapfiles.com/get/shellexview.html

and d/load that.Once you have unrar it open it up and sort the list by type.Then go down to Context Menu and find nView Desktop Context Menu then disable that one.

Try that out and let us know if it works as it seems to have done the job for me.

Cheers

Well, that seems to have fixed it.  How did you come up with this solution?  And I wonder why it suddenly started happening?

At any rate, thanks for the advice.
