I have been having freeze up problems, but have not yet connected it to RP8. Will go on the search. I never have freeze ups during the radio show, and for the most part am Out of all other programs except Crystal Audio all the time. My understanding is that Crystal Audio is my sound driver and I don't dare EXIT it (that from Joe O.)I will try to see what is going on...........freeze ups DO seem to date from when I down loaded RP8, but I don't know Jack.
