The first time it was mentioned, RD asked the poster about USI-LS, but didn't mention if it was the cause or the cure. No real solution was offered, and so I asked. Sorry.
But, yeah, USI-LS seems to cure the problem. I was using TAC LS before, and assumed it was supported, but I suppose now it is not.
Thanks!
I think jd284 touched on the real problem.
