Middle click menu in wordcloud

[lemings]

I'm trying to get gmusicbrowser working like I had it when I was Debian (I'm on a variation of Arch now). I'm not sure if it's a version difference, or if something in the new distro is interferring with the bind, but in Debian I was able to middle click an item on the wordcloud view, and it would pop up the album/track popup. If I try doing this now, nothing happens, and if I right click on an item in the worcloud view, the standard menu pops up. I would very much like to get the album/track popup working, whether it be through middle clicking or if I have to bind it to something else; right click even.

Here's an example of what I'm talking about. The first menu to popup is the right click one, and the second menu over the album art is the menu that I was able to popup by middle clicking on an album.

I'm using the gmusicbrowser package from AUR, it's 1.1.15-7.
