more on margin kerning

[Idris Samawi Hamid <ishamid@lamar.colostate.edu>]

Dear syndicate,

Hartmut may be right that this is a pdfetex problem***, but the following 
example makes me think there is more to it. Indeed, the following is actually 
more to the point of my own problem:

Consider the following typescript type-test.tex and and example file 
hanging.tex. When TeX hyphenates the word, the dash is kerned into the margin, 
but when a dash is manually inserted, no kerning occurs.

Note: in this example neither `-' nor \hyphen works, whereas in the previous 
posted problem \hyphen did work. This makes me think that this is a macro, not 
an engine, issue. Please help!

Best to all and thnx
Idris

*** I am using ConTeXt ver: 2005.03.16, the full mswincontext.zip. If there
is a compatible up-to-date pdfetex binary out there please point me to it (or 
send it to me)!
