[kde-linux] How do I disable the popup which appears when I change workspaces?

[Mun Johl]

Hi,

My Platform:
   CentOS release 6.4 (Final)
   Qt: 4.6.2
   KDE: 4.3.4 (KDE 4.3.4)

I would like to disable the popup that appears every time I change from
one workspace to another.  The popup provides a visual representation of
all of my workspaces and graphically shows my starting and ending
workspaces.  Although cool, I would prefer to disable this popus--if
only I could figure out where the setting lives.

Thanks.
