site manager duplicating sites

For some reason my dreamweaver has decided to show duplicate entries of sites
in the site manager. I have restarted IIS and tried the site editing scenario
someone here mentioned to no avail. I haven't installed anything recently and
am free of all ad/spyware and viruses? I have version 7.0.1 installed and it's
the first time I have seen this happen, and I have been using it for years now.

There is a technote on this at:

Thanks that did the trick. All these years I have been using an underscore in my site names and it just now started messing up the site manager? Oh well, I am all fixed up now! Thanks again.
