I am seeing this too after upgrading to 14.04, for example click on Files,
close the window, and clicking on Files then does nothing. Right click > Open
New Window still works.
Seems to be a rather serious bug, I wonder why more are not seeing it. Perhaps
it is an upgrade issue.

Title:
Apps locked to launcher only launch once per session.
Status in “unity” package in Ubuntu:
Confirmed
Bug description:
In Trusty:
An application that has been "locked to launcher", (including those
there by default) can only be clicked on once per session to actually
launch the application. After that it's unresponsive to clicks,
although right-click actions work.
Seems to affect all apps, including "Files".
To repeat, for any application not already on the launcher bar:
Launch the application using the dash.
Right-click on its launcher icon and select "Lock to Launcher"
Quit the application.
Click on its launcher icon. It should launch again.
Quit it again.
Click on its launcher icon again. It won't work this time. It looks
like dragging would work, but its operation as a launcher will not.
NB: I haven't installed any hacks eg: click-to-minimise. Seen this on
two systems upgraded from saucy to trusty. (One with AMD graphics, one
with Intel, so I doubt that's relevant either.)
