Maybe this is my fault. The simpleslides module works just fine these days and I "accidentally" updated the ConTeXt to the latest version:

context --version

mtx-context | ConTeXt Process Management 0.60 mtx-context | mtx-context | main context file: /opt/context/tex/texmf-context/tex/context/base/context.mkiv mtx-context | current version: 2013.02.13 18:06

and this small piece of code failed to compile:

\usemodule[simpleslides][style=BigNumber] \starttext \SlideTitle{Test} test \stoptext

This must be a consequence of the new MP instance code. I can reproduce the error, but I can't isolate it. I think the lines metapost > initializing instance 'metafun' using format 'metafun' metapost > loading 'metafun': /opt/context/tex/texmf-context/metapost/context/base/metafun.mpiv, using method: default metapost > initializing number mode "scaled" point to the source of the error, but I don't know where to look.

It seems that we gradually stop working other variations simpleslides module.

I have no idea what this is supposed to mean. Thomas

Thanks for the tip. After I've committed the lines with Field[Text][Text] in simpleslides-s-BigNumber.tex, it could compile successfully. I think this is a metafun bug?

Make sure that you run the latest beta. Indeed there has been a change to these Page related areas because in a recent mp there were several issues (most related to memory leaks), so I made a less demanding implementation. In the meantime Taco has fixed a lot of mp issues so upcoming luatex/mplib are okay (performance and memory wise). It all relates to mp now having scaled and double mode. (Alan is testing the mp double mechanisms.) Of course there can be other issues, Hans ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------

Do you mean "commented"?

Sure. I have no idea why I typed "committed."

So it makes sense to wait a couple of days before looking into this?
