/* Testcase for: Dialogs that save their positions when closing
   keep drifting downwards.

  To compile: 
  gcc -Wall -o test-gtk-move-3 test-gtk-move-3.c `pkg-config --cflags --libs gtk+-2.0 glib-2.0`

  To use:
  
  X -multiwindow &
  export DISPLAY=:0
  ./test-gtk-move-3
  
  Press 'Show', then close the dialog, then press 'Show' again.
  The dialog should reopen at the same place.
  In fact, it will reopen a little lower each time. Repeated execution
  will cause it to drift downwards.
