emptyspace|lclick on secondary display requires double click

I use emptyspace|lclick to open the taskbar and I love it, however on my secondary display it actually requires a double click to work.
I understand this is normal behavior when taskbars are unlocked, but in the case of a secondary monitor it happens even when all taskbars are locked.
If a fix is possible it would be appreciated, and thank you very much for this software (:
