I just discovered another issue that might have to do with these conflicts. The Custom Chat tab doesn't work. It's greyed out and I can't find a way to make it active. I just joined a guild, and they use it for guild chat; the guild leader said I should press F6 to get the custom chat, but that doesn't do it. It seems like there's no way for me to join the guild chat.
Please tell me I'm wrong and there is another way I'm not aware of.
