need help guys I am having an issue and im sure its something simple like a setting , but cad works fine when i send it to milling module cam opens with a black screen and no visible drawing however when i hover over where the drawing is supposed to be the direction for cutting arrows appear but no lines or anything else, Im sure its a setting and it has to do with the black screen instead of the typical white screen that the srawing used to open on but i dont know how to fix it. anybody got experience with this ? any ideas how to fix this problem ?? I have 13 on my laptop also and it works right except after the drawing comes up in cam on th white screen and everything looks good none of the command buttons work. somebody please help
