class=275253003-17062007>Trying to make use of "Class Documentation" (<A

href="blocked::http://dev.openlayers.org/docs/overview-tree.html">http://dev.openlayers.org/docs/overview-tree.html</A>):
the docu is fine, but I do miss information about 'what each entry is good
for' and brief examples about 'how to make use'. A list ordered by purpose of
classes and functions would also be good. Is there such a list which I have
not found yet?</SPAN></FONT></STRONG></DIV>

All draw controls seem to draw points and vertices south-east of where the
mouse-click occurred by about 1/2 of the diameter of the drawn Point-Circle.
That means all drawn features are miss-placed. Is this a bug or is it just
that I do use the draw feature wrongly? Source attached below. The website is
at this stage not public for administrative reasons;
sorry.</FONT></SPAN></FONT></DIV></LI></OL>

freehand mode by default. In freehand mode, the mouse is treated as a pen.
Drawing begins on mouse down, continues with every mouse move, and ends with
mouse up.<br><br>To turn freehand mode off, hold down the shift key
while digitizing. With freehand mode off, one vertex is added with each click
and double-clicks finish drawing. Freehand mode can be toggled on and off at any
time while drawing.<br>"</FONT><FONT color=#800000 size=2><BR></FONT><FONT
