Hi,

When creating a new megamenu, a machine name is automatically added, as in other regular Drupal modules. However, your error text tells me that "The machine-readable name must contain only lowercase letters, numbers, and hyphens. Which is fine, but the program prepends the inputted machine name with "mgm_" 

So the underscore causes an error, and the text box will not allow me to change the underscore to a hyphen. Has anyone else had this problem? It only seems to give the error when you try and save from the Configuration page. If you save from the edit area, everything seems to be fine. Very strange since other modules allow underscores.

I can work around this, but it is a pain and you may wish to fix.

Thanks!
