Hi,

If I use \setupcaption[number=no] and include a float with no caption, then all 
subsequent floats do not have a caption!

Here is an example (using 2011.11.29)

\setupcaption[number=no]
\startbuffer
\startnotmode[bugfix]
   \startplacefigure[location=here]
     Figure with no caption
   \stopplacefigure
\stopnotmode

\startplacefigure[location=here, title={Test}]
   Still no caption!
\stopplacefigure
\stopbuffer

\starttext
%% The float is shown with a caption here
\enablemode[bugfix]
\getbuffer


%% The second float does not have a caption now.
\disablemode[bugfix]
\getbuffer
\stoptext
