I know Evani is unlikely to still need this answer... but even so, someone else might find this useful.
I had the same problem with the spellbook scrollbar not working, and it turned out to be a conflict with "Subrace mini-mod for BGII".
Do you mean to say that as the Sub-race mini-mod uses the ToBEx's configuration file, or what ever that is, that, one needs to just go and fix it manually so the game enables both options, to be on ?
Had the mods made correctly, they would just patch the value in case the config was made... and not have overwrite.
But then the ToBEx would need to have no defaults. ...
Yep, Jarno Mikkola. my Mega Mod FAQ. Use of the BWS, and how to use it(scroll down that post a bit).
OK, desert dweller, welcome to the sanity, you are free to search for the limit, it's out there, we drew it in the sand. Ouh, actually it was still snow then.. but anyways.
