Windows [solved] Custom Menu items using PlayMedia not ActivateWindow

I have two XBMC computers, both running windows 7 64but; both using Transparency skin set up with the same options as far as I can see.

On both, i have added smartlists to favourites, and added those to the 3 extra custom menus.

One one, they are added using ActivateWindow, which is what I want.
On the other, it uses PlayMedia, which is what i don't want. How can I change it in the GUI?

I found a thread back in 2010, which said an entry was added to the skin settings scripts menu to control this, but it's not there in either of my installs. I have the latest version (4.0.5), both running on eden.

Edit: never mind, I found instructions in another post.
I had removed the "play in submenus" option, but didn#t realise i had to delete the menu and readd it.
