On my Windows XP system, IDLE opens windows too low, even the first, so
that the bottom is behind the task bar.  When I move the window up,
close, and reopen, it occasionally remembers the position but usually
forgets.  Always remembering would be nicer.

It also seems to me that the default should at least be centered, but
preferably even higher since new windows are cascaded down.

Or Configure/General could have an initial position for first window
entry just below or above the initial size.
