[RESOLVED] URGENT - creating word object with office.interops

[cengineer]

I am using the office interop to open word documents and saving as html to do parsing work. After a few executions I notice that in the task manager under processes there are still instances of WINWORD.EXE running. I have used the
following to close the object but it is still there:

wordApp.Quit()
wordApp = Nothing

How do I close this in order to avoid overhead? Any ideas appreciated
