BUFFY is BtS only!
Sure it is. My problem is not with BUFFY but with HOF1.74.004.
I have just upgraded BTS to 3.19, installed BUFFY and installed HOF1.74.004. Everything is working fine in BTS. No interface in Vanilla.
Shouldn't I be posting here? I did a quick search of no-interface problems and it's in this thread where they were mentioned.
