Bug Description

When setting up Ubuntu 14.04 with multiple monitors and showing the Unity launcher only in one of the monitors, the applications presented in the launcher can only be launched once.
The can be launched through the dash or terminal, or right clicking on the launcher icon and choosing "New Window" in Forefox's case for instance. But a simple click on the icon will no longer work.

If the launcher is present on all monitors this problem does disappear.

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

I have the very same problem, both on dual monitor and triple monitor setup.

If I have the laucnher on one monitor, it only works once. If I have it visible on all monitors, it always works.
This should bug is really annoying.

I have the same problem - dual monitors, only able to left-click-launch once if launcher is present on only one screen.

Affects me too, tree monitors with one launcher (AMD card).
I can open apps if I use the middle mouse button.
