Universal Email Insert Record to Email Log

WA's Universal Email logging system is generally working quite well. But I have one problem of a Java Script Error. I pass the current WA UserID through the Universal Email form to the email log record in the Insert Record dialogue. In some cases, however, I receive the following error message: "While executing applyServerBehavior in CreateEmailMessageWA.htm, a JavaScript error occurred." This occurs when I am trying to bind the UserID from The WA email form to the email log database (where I have created a new field of UserID). Any suggestions to solve this problem? Where is the file CreateEmailMessageWA.htm lcoated? It does not show up in my finder. I was hoping to even make the change manually. I could totally uninstall the Universal Email behavior and reinstall, with hope that this would fix it, but I would like to avoid this if possible because email functionality can be tricky. I will do the uninstall if this is your best recommendation. Thanks you.
