Yes Kevin, twice, before that I've deinstalled the 3CXCRM11 module and Desktop Components and rebooted the Win 7 ultimate PC. I will wait for next build, before trying again. Also I didn't managed to use 'Call notify of external program' and 'Command Line API'. These features are widely used by some of my V.11 customers. Looks like V.12 is too early to be used in commercial environment (still no official release), but even for tests. Also the softphone must be working as phone, not only as replacement of MyPhone. It is good to get rid of Silverlight, but this is not enough.
