Bug Description

Binary package hint: unity

Normally the Unity launchers will only allow you to open a single copy of a program, eg you can only open one file manager window. Subsequent clicks open the window selection...thing.

But if you click the launcher eg 3 times before nautilus loads, you will get 3 nautilus windows. As soon as the first window opens this stops happening.

To reproduce:

1. Close all nautilus windows
2. Quickly click the nautilus icon lots of times
3. Watch loads of nautilus windows open

I don't think this is a bug. It's more a feature.

If it's a feature, then the button should be responding four times (each within 100 milliseconds) to show that it has responded!

We no longer respond to multiple clicks. When the startup notification animation is playing, we do not launch new instances.
