Word 97 new instance when accessing a document

[Ron]

Hello,
Using Office 97 - For some reason when I open a document
from say explorer, it always opens a new instance of Word.
I know that is by default in Office 2000, but I have never
seen this happen with 97. Has anyone else seen this? Any
suggested fixes?? I can live with this, but it is bugging
me.

Thank you!
