I am pretty sure that after installing 11.10 when an application had two or more windows open and I hovered over a unity bar icon with little white arrows (one for each window), I was getting a window thumbnail for each window of that application.
But I don't see that any more.
Does anyone know how to restore that?
For me, this didn't help. I had to also remove the Truecrypt lock file as per these instructions.
In terminal enter:
rm ~/.TrueCrypt-lock-USERNAME
Where you replace USERNAME with your username.
One suggestion is to use the default Launcher capability to display all the windows of a running application.
Press Win - also known as the super key to display your Launcher - or move your mouse to the left hand edge to display the launcher.
You'll notice that applications with multiple windows will have "dots" next to them.
Click once to bring the first window to the foreground. Click again to reveal all the windows for that application:
From that view you can choose which window you are interested in.
Alternatively:
Use the keyboard shortcut Alt+`
That "`" is called a grave - let go of the grave without letting go of Alt and then repress grave to cycle through the windows group.
