Make sure you are implementing the workaround as suggested, to the Markup pane.
Aha! I didn't realize that was the suggested way to implement the workaround. I just did as you commanded, and it worked beautifully! After two weeks of despair and struggle to figure out how to proceed, I think this is all I need to get back to writing. Thank you!
Last question (for now, I think): Using the workaround via Markup, the name of the equation is suppressed, and instead I get "Equation 1.1". Is there a way to have the "E" in "Equation" be lowercase, instead of upper?
