I'm also affected.
Everything is ok except the singe leftclick to start the application.
The click is recognized, because once it is started I can switch focus to the application with a single leftclick on the icon.
It just doesn't start the application.
The problem is only there if the launcher is only visible on one monitor (which one makes no difference), making the launcher visible on all (in my case three) monitors immediately fixes the problem.
Some version info:
libunity9:amd64 7.1.4+14.04.20140210-0ubuntu1
unity 7.2.0+14.04.20140416-0ubuntu1
unity-services 7.2.0+14.04.20140416-0ubuntu1
