Overfull boxes using m-cweb

[Edwin Wisse <edwin.wisse@xs4all.nl>]

Hello,

I am running into overfull boxes when including a weaved cweb file into
a context document.  The original reference to the cwebmac.tex file (the 
plain
TeX macro) is commented out and replaced by \usemodule[cweb]. The cweb
macros appear to expand something into \*11ptmmmt* which seems to have
something to do with it.
Is there anyone here with experience and deep (Con)TeX(t) knowledge who
understands what is happening?

Regards, Edwin
