Hello ConTeXist.

I have just installed the latest version of ConTeXt standalone. When I compiled an my old source code, I received an error:

! You can't use `\Ustopmath' in restricted horizontal mode! You can't use `\Ustopmath' in restricted horizontal mode! You can't use `\Ustartmath' in restricted horizontal mode! Inline math should end with \Ustopmath

This strange error is caused something in my extensive library for handling CSV files. I'm not sure why, because in library I am not use with any mathematical mode.

I am sorry, but at this moment I am not able to reveal the mistake to be able make a minimal example. Some of the older versions (not necessarily penultimate) worked without problems. Is there someone who help me start look from which point look for a mistake in my code library? Thanks for the information.
