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.

My preliminary investigation suggests that this is not an Emacs bug. I
believe the behavior you have described is a feature of Windows 7. I
followed your steps in Internet Explorer, Mozilla Firefox, and TextPad on
Windows 7 and all three applications behave the same way. When I drag the
windows up and then immediately back down, the window height changes in all
three applications. What I believe is happening is that the drag up and
immediately back down action is somehow being interpreted by Windows 7 as
being equivalent to the restore command.

Indeed, this is Aero Snap at work. It can be disabled, apparently,
though I find it quite useful and have never tried.

How about adding an entry to etc/PROBLEMS about that?

Well, I don't really agree that we should document in etc/PROBLEMS
something that it is not a bug but a feature of the OS, and whose
effect is not limited to Emacs in any way...

PROBLEMS is not only about bugs, it is also about any issues that
could possibly _look_ like one.

It seems we disagree on whether this one looks line one. You don't
need more than one day or two working with Windows 7 to notice the
effect.

Hello,
For what it is worth, I am of the opinion that this issue should not be
documented in etc/PROBLEMS. The reported behavior is a feature of Windows 7
as Eli Zaretskii pointed out.
It may be worthwhile for this feature to be documented on the "EmacsWiki:
Category WThirty Two" page though.
I am also of the opinion that we should not attempt to cause "the 'snap'
messages to reset [to] be ignored by Emacs" as Bob Floyd suggested in
another message. Any attempt to do so would make Emacs behave differently
from any other application designed for Microsoft Windows. This is
something we do not want to do. If anything we want to decrease the
differences between Emacs and other Windows applications, not add to them.

This seems to be specific to Windows 7. I cannot reproduce it on XP.

It is new to Windows 7. As Juanma Barranquero pointed out it is a result of
the Aero Snap feature which is described at <
http://www.microsoft.com/windows/windows-7/features/snap.aspx>. As Juanma
Barranquero said, this feature can be disabled. See <
http://social.technet.microsoft.com/Forums/en-US/w7itproui/thread/e8dfc091-2d9a-4f42-9d1a-97d74af513c5>
for details.

Ah, Windows "Snap", yes. Thanks:
http://windows.microsoft.com/en-us/windows7/Expand-windows-vertically-on-the
-desktop-using-Snap
Notepad has the same behavior, so Emacs is behaving just like notepad, and
the above link indicates this behavior is engineered into snap.
I agree that dragging the top or bottom Emacs frame edge to a screen border
is very convenient to obtain a full height Emacs frame.
However, I just turned off "snap" on my system because the "snap" behavior
described in this not-a-bug report is awful.
Maybe it's just me, but when I attempt to move an Emacs frame horizontally
and observe my frame dramatically shrink and all windows therein
repositioned irreversibly it flusters me. I would recommend the "snap"
messages to extend the frame to full height be accepted by Emacs, and the
"snap" messages to reset be ignored by Emacs, if that is even remotely
possible.
