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 ------------- (/usr/local/texlive/2008/texmf-dist/tex/context/base/sort-lan.mkii)) [1.1] !
