Using Front Page 2003, I work on three virtually identical dynaminc web
templates (*.dwt).  Only difference is the number of columns -- one with one
(full page) column, one with two columns, and one with three columns.

The dwt files with multiple columns save changes just fine and go onto
update the linked pages.

The dwt file with one (full page) column NEVER saves without an error and
opening a new page.  No attached files are updated!  
When I go back into the page the changes are there.
If I try to save the page, the error occurs.  

There is no clue as to why this happens.

Any ideas about what may be the cause?

Thanks.
