Not in front of my LW machine now, but, try going into the Edit Menu Layout command in Modeler. As I recall there is a drop down box that gives you some choices for the different LW versions. Check if there's a 9.6 choice. It should reset your menus to the default menu layout, then check if the command is there. Could be way off here... I'll check later, or if someone else could verify...

EDIT\\ OK, go into the Edit Menu Layout command, click the button that says "presets", then choose "Default". I then found the Untangle command under the Modify tab, Translate\More. If you still don't find it then I don't know what else it could be.
