Please note that official support for this menu version has now ceased. There are still plenty of users, though, and the forum is still running. Some of our long-time users may be able to help you out.
I noticed a new version is out today (3.4.06). My question is: how exactly do I make the upgrade from an older version? How do I keep my old settings in a comfortable manner? Do I have to change both mmenu.js and menu_array.js?
One other question: is this a beta or a regular? How can I tell?
....complete the download and just copy over your previous mmenu.js file. Normally I don't modify menu_array.js, but watch to see if version number mentioned in the preamble of the file changes just in case.
as for beta or regular version...i believe this is a work in progress
