Just downloaded the latest version of Xperl Unitframes and got it working fine.
Only problem is I can't right click my own portrait, nor my target's portrait. The only thing that could conflict with it, that I can think of, is Clique. Checked the blacklist, and none of the Xperl tabs are checked, so it's not that.
Try checking the Xperl tabs in the Clique setup. You're looking at the blacklist, which means that ticking/checking these will not be registerd by Clique.
That should allow normal clicking on your portrait.
