Won't export as PDF or PNG when using \overbar{}

[str55]

Hi,

First off thanks for this great tool!
I have noticed that when I include \overline{b} in my diagram, the export to pdf and png fail. It looks fine on the browser, but the pdf / png I make cannot be opened. When I leave them as b, the export is successful.

Thanks,
Steve

Found a solution. Wrapping in $ $ like:
$\overline{b}$
fixes this.
Please disregard.
