Winword.exe multiple instances

[RGBrasel]

I use a Help Authoring Tool (Doc-to-Help) that uses MS Word as its document
generator. Certain functions aren't working properly (Documenter for .NET,
which generates MSDN style-documentation for assemblies), and just a few
minutes ago, while attempting to delete some folders, I noticed 7 instances
of Winword.exe were running with no open documents and no open MSWord.

Given that I have recently installed a new build of my Help Authoring
software, is it possible there's something wrong with my Word 2003
application?

Thanks!
