+It has to be noted that the API for drag and drop in wxWindows is not
+yet finished which is mostly due to the fact that DnD support under
+GTK 1.0 is very rudimentary and entirely different from the XDnD
+protocoll used by GTK 1.2. This also entails that not all of the documentation
+concerning DnD might be correct and some of the code might get broken
+in the future. The next release of wxWindows will be based on GTK 1.2
+and will hopefully include a much improved DnD support. The general
+design on the wxDropSource side will be the same but especially the
+wxDropTarget is almost certain to change.
+
+Note that wxUSE\_DRAG\_AND\_DROP must be defined in setup.h in order
+to use Drag'n'Drop in wxWindows.
 
 This overview describes wxWindows support for drag and drop and clipboard
 operations. Both of these topics are discussed here because, in fact, they're
