The \limits command only works for math operators, but we enable MATH_LIMITS whenever there are limits. This leads to an error if the limits are not on a math operator. See the attached error.lyx. We can use \mathop to convert to a math operator, and then there is no error. See no_error.lyx.
An alternative would be to just disable MATH_LIMITS if the symbol is not a math operator. Any opinions? Scott
