Hello,
I use "\expandparameters" in a macro definition.
--
\expandparameters\setupbackgrounds[page][background={\currentvalue,#1}]
--
This works in MkII (texexec), but doesn't work in MkIV (context).

If I define all layers in a single declaration, the results with MkII and MkIV
are identical.

Should this work? Or do I have to add something for MkIV?

Thanks and kind regards

Erik
