In 3.7, a full click (red button) on the desktop opens the World menu and
selects whatever option happens to appear under the pointer at that location as
soon as you move the pointer.  Or, if you move the pointer away from the menu,
it disappears.

This is inconsistent, aggravating and, possibly, dangerous as the "save"
command could be invoked unexpectedly saving your image before you're ready.

This was not a problem in 3.6, nor is it a problem in 3.7 for other menus such
as the "Personal" menu invoked with the yellow button.  Also, using the escape
key to bring up the world menu seems to behave correctly too.
