Dreamweaver not default editor?

Something new to my PC:
Dreamweaver is no longer available as a right click option on my on Win 98 PC.

When in Windows Explorer (or My Computer) if I hightlight an HTML file and right click on it I used to be able to open with Dreamweaver now DreamWeaver no longer shows as an option!

MORE... If I chose "open with" and scroll down to DreamWeaver there are 2 entries, one is "DREAMW~1", the other is what you'd expect: "DreamWeaver".

Thx
