I found a way to duplicate this issue.
Run the following script in a terminal:
#!/bin/sh
sleep 10
update-manager --no-focus-on-map
Before the update-manager pops up, log into a "Guest Session". Wait
about 10 seconds, then switch back. Enter your password at the greeting
screen. Then you'll see a 'Enter the root password' type of box since
update-manager needs root permissions. I hit cancel on that window.
Finally, there will be an update-manager icon (the green A with a
progress bar through it) in the list of program at the left, but it
can't be clicked on to bring it up. It can be right-clicked to close
it. Also, alt-tab shows it, but won't switch to it.
Potential pre-requisites: I'm running on a laptop with an external
monitor. They are different resolutions. Also there is an update
available to install. I'm running Ubuntu 14.04, but I've seen it on
12.04.
Interestingly enough, my "Guest Session" runs on tty F8, meaning that I
can press Ctrl-Alt-F8 and see the guest session. When I press Ctrl-
Alt-F7 I get my normal session.
I have no clue how to continue looking at this problem.

Bug description:
Update manager is showing up in the dock but I can click on the icon
all day and nothing happens. Similarly if I do Super-S or Super-W it
doesn't show up anywhere.
Even if I alt-tab to the application nothing shows up. This happens
only when update manager runs on its own. If I kill it and then launch
it myself it comes to the foreground just fine.
I'm not 100% sure whether this is a unity, compiz, or update-manager
bug but so far my bet is on unity.
