Charles,

I just started using dot in org-mode (and I love it). Had no problems at
all so far.

Here are my specs:

* Emacs 25.3.1
* Org 9.1.2
* Here is my .init file
<https://github.com/SeaDude/dotfiles/blob/master/emacs/.emacs.d/config.org>
* Here is an example of dot in action in orgmode
<https://raw.githubusercontent.com/SeaDude/wtd-gitbook-pres/master/gitbook.org>

Maybe you can glean something from this that helps.

Cheers
