 Windows 95 and Windows NT up to version 4.0 do not support help text
 for menus.  Help text is only available in later versions of Windows.
+When "ClearType" method is selected as the "method to smooth edges of
+screen fonts" (in Display Properties, Appearance tab, under
+"Effects"), there are various problems related to display of
+characters: 2-pixel trace is left behind when moving overlays, bold
+fonts can be hard to read, small portions of some characters could
+appear chopped, etc.  This happens because, under ClearType,
+characters are drawn outside their advertised bounding box.  Emacs 21
+disabled the use of ClearType, whereas Emacs 22 allows it and has some
+code to enlarge the width of the bounding box.  Apparently, this
+display feature needs more changes to get it 100% right.  A workaround
+is to disable ClearType.
 There are problems with display if mouse-tracking is enabled and the
 mouse is moved off a frame, over another frame then back over the first
 frame.  A workaround is to click the left mouse button inside the frame
