[Gnump3d-users] add .htm

[linuxhippy]

I have some pages that are .html and some that are .htm that I have linked off 
my index page.  I have a menu bar that I would like all these pages to display. 
 I am able to change the menu bar file and that changes in all these pages by 
putting this line in my .html and .htm files:

<!-- include="menu.tmpl" -->

This works fine in the .html files but doesn't work in the .htm files.  Why?
