Convert txt files to cfg

[Clodius]

Absolutely basic question.

In RTW the preferences file was a .txt file that could be simply edited and saved.

in MTW2 its a .cfg file.

I can open it using notepad but when I hit save it save it saves as a .txt file - and there is no option for saving it as a .cfg file in Vista.

Just renaming it by adding .cfg on the end creates a file called medieval2preferences.cfg.txt

Thus I'm stuck with irritating arrow markers, banners etc

There must be a really obvious way around this but I can't see it.
