Question: The Update Manager recently started itself and found two updates. I can tell by the icon in the launcher. The icon has a (2) on it and a little white arrow saying the application is running. I can also see the update-manager process in a 'ps -A' list. Alt-Tab also shows the Update Manager.

The problem is I can't get Update Manager to show up. If I click on the icon or Alt-Tab to it, nothing happens. I've never had any issues starting it manually, but when it starts on it's own after finding an update, I can't switch to it.

What can I try to make this work better?

Answer: 
This is a bug with Unity, it seems to happen with LibreOffice too. I don't think there is any fix yet, Unity is still being worked on. Link: <https://bugs.launchpad.net/ubuntu/+source/unity/+bug/942222>

You can just update manually using a terminal by typing these in sequence:

```
sudo apt-get update
sudo apt-get upgrade

```

If the update manager is bugging you, kill it with this command:

```
killall update-manager

```
I've seen scenarios where application windows end up outside of the screen area. Sometimes its caused by having windows placed on secondary screens then disconnecting the screen. Leaving the application "unreachable"

* Go to the desktop that seems to have the application running.
* Make sure the application is selected with alt+tab.
* Press alt+space + m (m for move, if you use english ubuntu) drag the
mouse cursor to the center of the screen.

Your application window should be attached to
 the mouse cursor if the issue you had was this.
