Hello,

I'm having some problems with "simple-slides".  I'm pretty new to ConTeXt - so I've probably done something silly.  
When I try to use the \IncludePicture command like this:

\IncludePicture
[horizontal]
[test] 
{A Dutch Cow}

I get the errors like "! Missing number, treated as zero" and "! Missing = inserted for \ifnum"  (see below).

I'm using MacTex-2008 distribution.  I've also tried the current context minimals - but got the same result.

thanks
Glen
