A user wrote in because they button they were using to show the Desktop was no longer present.  We all had a good laugh when we saw their attached image.

The problem was were all laughing for the wrong reason.

They were not in fact using the close button on a window to show the Desktop as the above may suggest.  No.  They were actually using the Show Desktop button at the far end of the Taskbar.  We should have been laughing at the oddness of the image.

Take a closer look.

In reality it is important to understand what the other is saying.  This will ensure that you are laughing for all the right reasons.
