There are some versions of Max (early versions of 3ds Max 2012 and now in 3ds Max 2017) that do not update the menus and macroscript's (functions for menus, keyboard shortcuts, buttons, etc).

This means that when you update WW/WW Pro, new or changed functions that relate to the menus and macroscripts are not automatically updated in affected versions of Max.

You can manually update the macroscripts and menus by doing this:

1. Open the global settings by clicking Wall Worm > Wall Worm Settings
2. Click the Update Menus button under the list of presets.

If you do not see the Update Menus button, you do not have the latest version of WW installed.
