Problem:

 

  Emacs frame height setting is lost - it's actually restored to the height
on startup - when the entire frame is dragged up-then-down.

 

Reproduce: On Windows 7, Emacs 23.3.rc2

 

  1. Start emacs, the visible frame is about 40 lines high, positioned
somewhere away from the desktop edges.

  2. Drag the bottom of the frame window by pressing the left-mouse button
and dragging the lower frame edge downwards on the screen toward the

      Windows 7 task bar. When the Emacs edge reaches the task bar notice a
small flash is visible, indicating the maximum extent. Before releasing the

      left mouse also notice Emacs displays an outline of the upper frame
edge that extends to the upper extent of the desktop.  (Aero effect??)

  3. Release the left-mouse and observe the height of the Emacs frame is
tallest, extending from the top of the screen to the task bar.

  4. Left-mouse press on the title bar, move the frame up (it doesn't
actually move it because it's already at the top) then drag the frame down
all in one

       movement. 

  5. Notice the frame height jumps to it's original height as the height
setting is lost and the frame height returns to the original starting height
in step 1.

 

The frame height should not be lost when attempting to move the entire
frame.
