Well, I just seem to have found the problem, but now I really feel stupid!! :( I have lost a lot of time and never occured me that the problem might be windows 2000!!! it works fine on ME or 98 !!!! is there any notice of poser being incompatible with Windows2000? if not, this bug should be posted to check if there is someone else with this problem ( it stil might be my configuration) , and warn CL about this. maybe they have a patch or something.. dunno. anyway Thanks for your promptly Help to this Now feeling terribly stupid guy! :) thanks Az
