Hi Hans, Thanks for the new beta: as a matter of fact it seems to be much faster the previous ones, even with many backgrounds!
I wanted to submit a small bug with the « \prime » in math mode: the following gives an error %%%%%% begin example.tex \starttext The function $\exp$ is the unique solution of \startformula u'(x) = u(x) \quad u(0) = 1. \stopformula \stoptext %%%%% end example.tex The error message is: \301>c ->\egroup <to be read again> ( l.6 u'( x) = u(x) \quad u(0) = 1.
