After installing the plugin, and binding the attack3 i'm able to pull up a menu, but unable to build anything or spawn anything using it.  I am able to change the grade of what i build after exiting it, but can't build using right mouse or anything. 

Seems to me like its not working.  
Also, is there a Toggle command to enable / disable the plugin?   I don't want it to load whenever i accidentlaly hit middle mouse.
