while finishing this:

I was experimenting with fonts.  Using xetex, I simply added :

\definetypeface[Optima][rm][Xserif][Optima]

\setupbodyfont[Optima]

Fonts are ok (Optima is used).

I saw that many tmp .rli files are generated. Apart form the increasing compiling time, the first problem is that I had to run several times texexec --xtx in order to generate them all. Is it normal? 

Most important it behaves strangely with layers using pdfs figures.  Color is not applied, or typically they are not shown.

What am I missing?

Many thanks 

Best

PS: no news with the old xetex question concerning fonts in figure? It seems that both the problem are related to the use of pdfs to be inserted in the ConTeXT file.
