When you have aspect correction enabled the shortcut bar hovers "in" the game.
Now, grab any item and drag it over any button
-> the action of the button will start and when you end this, the item is gone. For example, drag it over the notebook button, the notebook will open, close the notebook with ESC -> item gone.
I think that's one of the reason the face_stats gump is checking for dragging (the other that you can drag'n'drop an item to the face).
Bad bad bug!
