Am I ever glad I found this post. I just installed LiteStep last night and was encountering the same problem. I am also running ME (stop shaking your heads in pity!). I know for a fact that I have at least one other tray monitor loading at start up and I haven't a clue which of many programs I have installed to try out in the past may have put it there. I will try disabling it and hope it solves the problem.
