Okay, closing ProE and restarting has allowed the option to work. I guess for some reason ProE doesn't really load the config.sup in the current session.
Strangely, after restarting I checked the config.pro file and the option is still greyed out, but it is green in the config.sup file, and it is green in the current session.
I guess the grey dot in config.pro means it's being ignoredpro even though the setting is the same as config.sup.
Thanks Kdem, I now I have a useful hole option, I don't have to sketch them anymore!
