I would be happy to try to help with this issue. I am new Gtk app development, but not development in general. If you can point me in a direction, I would be happy to try to fix it.

[JosephMcc]

That's because your theme is installed to ~/.themes instead of /usr/share/themes/ so apps that run as root, like the dialog boxes you are talking about, can't use it.

@JosephMcc thanks for the quick response. That's obvious now that we are talking about it.
