Using Mint 7.0
Having installed AWN I had a problem getting my favourite goodies--Firefox etc installed on the launch bar--dragging from the menu wouldn't work. I Found however that they would 'stick' if I dragged them to the desktop then to AWN--alas,deleting them from the desktop would make them disappear from AWN.
Eventually I tried changing the Mint Menu to the standard Gnome Menu and Bingo,it works like it should!
A bit frustrating because it seemed to work ok in Mint 6.0
