Hi Terry,
It sounds as if that menu was created with a very old version of DHTML Menu. I think Sothink stopped using stm31.js with Version 6 and the current version is 9.7. I don't think it's a good idea to run JavaScripts that old; even if you were able to make minor modifications to the code you would likely run into browser compability issues.
If your friend wants to keep and upgrade the menu, I suggest spending $65.00U S on the current version of the DHTML Menu program (
http://www.sothink.com/product/dhtmlmenu/). Your friend may not have the .pgt file for the menu and that is essential to recreate and upgrade the menu. Once the new program has been purchased and registered, send the menu.js file and the registration information to
support@sothink.com and request that they recreate the menu's .pgt file.
Regards,
Bill
