I notice that the dialog in 14.1 has a few more theme options than the previous version. The dialogrc in Soma doesn't quite work with it so I've uploaded a new version:

Note that now the ~/.soma/dialogrc is renamed to ~/.soma/dialogrc-$VERSION in the latest version, but not in 2.8.5, which is in 14.1.
There is a package available for 2.8.9, or you could just copy the dialogrc in the source dir to ~/.soma
Enjoy
