One thing I have noticed with the Crosspack version is that the first time I use it after powering the mkII up it works fine. Subsequent runs against the mkII without a power cycle work but there is anywhere from a 5-30 second delay before the initialize happens. I believe I've posted to this list about it. I found that the patch that skips the sign-on fixes that as well.
