I have had some trouble in the past using explorer. I am trying to put an assembly with many sub assemblies onto a CD. Explorer sometimes prompts me a second time to find the assembly even though it is listed in the first box ( from ). Then it copies just the assembly and not the children to my (to ) directory. Even though the" find children" check box is checked. Other times all seems to go welll but the configurations of all my toolbox parts are lost. Giant size default screws are inserted. I don't use this very often so each time is like the first. Can someone give me some tips to accomplish this seemingly simple task? Thanks in advance. Don
