strange error message when updating template - receiveArguments error

Hi

Win XP Dreamweaver MX 6.1

Revamping a website so I made a folder to dump the old one in and then used my old (now empty) www-docs folder to start creating new template page for site. On saving the template I get a weird error:-

While executing receiveArguments, the following JavaScript error(s) occurre:

At line 45 of file "c:\Program Files\Macromedia\Dreamweaver MX\Configuration\Menus\MM\File_Save.js":
exception throw in native function

Options given are OK or Cancel

If I do ok it shuts down Dreamweaver.

A search for receiveArguments or receiveArguments error draws a blank in the support pages

Any ideas????
