Thank's for your example! But I'm sorry to say, I didn't get it. When I run context on it, it results in a 2x2 matrix of pictures.
Two of them show some reaction (change the color somewhat)
when I click on them. (the cows don't). That's all.
Maybe it has to with the following lines in the log file:
...
interaction : active
references : unknown reference [][VideLayer{1}]
references : unknown reference [][VideLayer{2}]
references : unknown reference [][VideLayer{3}]
references : unknown reference [][VideLayer{4}]
...
I tried the following example from the Wiki:
=======
\defineproperty[my-hasitations][layer][state=stop]
\startproperty[my-hasitations]
To \ConTeXt\ or not to \ConTeXt?
\stopproperty
\button{Show Decision}[VideLayer{my-hasitations}]
\button{Hide Decision}[HideLayer{my-hasitations}]
\button{Toggle Decision}[ToggleLayer{my-hasitations}]
========
This produces the analogous messages for these three buttons.
My Context Version - "MTXrun | current version: 2010.11.03 19:42"
My LuaTeX Version - This is LuaTeX, Version beta-0.63.0-2010090921
on Debian AMD64. I looked at the files with Acrobat Reader 9 on Windows XP
(BTW. I also tried this completely using a MiKTeX 9 Installation on WinXP without
success)
Am I missing something?
kind regards
