The latest stable (ConTeXt  ver: 2006.04.06 23:00  fmt: 2006.4.7   
int: english  mes: english) release fails to compile a file that  
worked previously and returns the error message:

I do not know if this is a problem with the new release—or whether I  
should make changes at my end to get it to work again. Any suggestions?
