The "no parking" term is mine, I needed an expression to describe this 
appearance (and, as you already noticed, I'm not a native speaker.., sorry).

It means: no layout assigned, and asks for some action: guess, which..
If you want to try yourself, read my other mail, load mainframe.ui as you sent 
it to the list, and try to archive, what I sent in.

You can drop a horiz. spacer into the button group. Drag it until a little 
blue line appears right to the buttons, but still inside the button group: 
notice, that you can add and remove spacers in already layouted elements! 
Next, click somewhere in this tabs background and assign a vertical layout. 
Repeat for all other tabs. Finish with assigning a layout to the toplevel 
widget (I used grid, IIRC). Some tabs have misplaced spacers, compare with my 
mainframe.ui on how, *I think*, a sane layout should display.
