Alright, after much futzing around with things (basically just trying the same things over and over, restarting ST3, over and over, yada yada yada), it seems to be working properly now. For now ;-p Of course, having to be this stubborn to get a plugin to activate still seems to suggest some small incompatibility between BS and ST3 or beta bugs just on ST3s side. Here’s hoping it keeps working, because other than this little headache, ST3 is looking like even more of a hotrod than ST2 was after I’d tricked it out.
Thanks tito.
