xcode 3.2.2, can't see nib design view

I recently updated to xc开发者_StackOverflowode 3.2.2 yet now when I click my .xib files, I can't see the view window where I can drag/drop stuff, I only see the inspector panes and can't get the design view to show

Double-click the view in the xib object viewer (normally this would cause the view to appear and become active) and you will see the object viewer lose focus. Press CMD+W (to close the invisible view) and then double-click to open it again. It should appear on your screen now.
