I don't know.

MarkupExprPlus seems to disable the core markup expressions and add its 
own full replacement.

It processes not only add/sub/mul/div but all core markup expressions, 
and any custom ones you may add.

See if the problem appears with the latest version of MX+, and maybe 
DFaure can reply better than me.
