... switch back to 2D model space...

... from 3D perspective projection in ACAD 2007?

I have accidentally messed up with the workspaces while exploring the new version. Now I can't go back to the normal 2D view. All I have is that gray-with-lines as background in ALL workspaces.

Many thanks

EDIT:
BTW, I wanted to start ACAD with the 'classic' style. Mine always starts with a 3D perspective view.

At the command line type WSSETTINGS.

thanks for the reply ReMark but that wasn't the answer I was looking for...

however, I managed to find the answer myself when I noticed that ACAD2007 was loading "acadiso3d.dwt" upon startup. so, I quickly went to Options>Files Tab> Template Settings and changed the "Default Template File Name for QNEW" from acadiso3d.dwt to acadiso.dwt.
