Hello Marius,
I saw you email on cf-talk and have not been able to post yet on it. My
post keep comeing back. I just loaded CF sever on my Windows ME system at
home and the Administrator of CF Server will not open in Windows ME but it
will in NT.
It displays a download box which will not let me view the web page. I have
installed CF 4.5.
Would you know anything about this?
