The freeze option does not recognize and freeze user contributed graph scheme files...

[meadover]

For example, you can install the scheme "s2clr_on_white" from inside Stata by typing:

- search scheme-s2clr_on_white.scheme

Once installed, you can find the scheme one of two ways:

- which scheme-s2clr_on_white.scheme
- graph query, schemes

But I can't seem to include this user contributed file on the list in your option -adolist()-. Perhaps this is because -scheme- files do not end with the extension -ado.
