I am really puzzled by this problem I'm having with XP Professional SP2. I have taken a 3.6 BCM to two different locations with XP SP2 and it works fine. It is only not working at one location. This file and/or hack is not evident, reflected or required at either of these sites, yet when added at the problem site, it does not seem to make any difference? Any ideas or anyone else come across or overcome this problem? Sooperbohl, you said it can be a real pain to get it to work initially, why?
