Hi!

I am looking to METAFUN and I wanted to follow the Growing Graphics demonstration (page 314-- ).

I copied the instructions and everything went OK up to page 320; the command to place the figure with a button returns an error:

\stopoverlay}}

1 >> %% !TeX program = ConTeXt

2

3

4 \starttext

5

6 \startbuffer[a]

7 def start_everything = enddef ;

8 def stop_everything = enddef ;

9 \stopbuffer

10

11 \startbuffer[b]

The control sequence at the end of the top line of your error message was never

\def'ed. You can just continue as I'll forget about whatever was undefined.

It looks like \stopoverlay is not known!!! but \startoverlay is recognised!
