Recently I reported 2 problems related to metapost usage: 1. the loss of transparent color handling 2. textext not being able to handle %'s as in textext("15\%")
The first problem seems to be solved by Taco's remark:
Believe it or not, but this is a known problem within web2c. It is triggered by an interaction between the new texexec and having two different entries in texmf.cnf for Metaposts memory size, for example like this:
main_memory.mpost = 500000 main_memory.metafun = 3000000
Now, the metafun format is generated as "mpost", but the graphics are created as "metafun", and the different memory sizes make the specials go disappear.
I checked my texmf.cnf in teTeX's main directory ../teTeX/share/texmf (the one I use) and to my surprise found the complete absence there of main_memory.metafun although context itself is present. Addding and regenerating metafun repared the "broken transparency" problem. I have further to investigate why apparently context.cnf seems not to have been read or being effective, because there main_memory.metafun is present! Thanks Taco for your remark, although it took some time before I realised that this remark of yours could be the key to the problem. However the breaking of the handling of "\%"'s in textext was not solved by this repair. Will there be a fix in the forseeable future? Taco wrote in reply to my first signalling the problem:

I am afraid a serious error has been introduced into textext in the last update(s).
This used to work in metapost for typesetting text with a %-sign:
label(textext("66\%"), origin);
Now the % somewhere ends a line prematurely because the job aborts with: ! mpx file ended unexpectedly.
Can Hans please repair this, suddenly a lot of my typesetting is broken.
Verified.
Thanks for analizing this, I was wondering where those ! mpx file ended unexpectedly. messages came from in a document Mojca sent me.
