Nice yellow letters....I see very well your post.
Did you try Env 15 with TWoS 2.09? For example, I think, you need to delete the sh.sdl file from Env 15 and conserve the file from TWoS. Also, see what files overwrites Env 15 of TWoS with JSGME and think what could be the possible conflict. First of all, the AI from TWoS is calibrated with his own enviro, so this could be a problem
I didnīt try it, so take my comments only as a sugerence.
