SW 2011, sp2 -64 bit version. Why does pack &b go seem to hang when I ask it to also include drawing files? Am I just not waiting long enough. I have sat there watching for 15 minutes with no luck. Any clues? What I end up doing is saving without the drawings then copying them manually into the new folder after the fact, but would rather do all in one shot. These are moderate sized assemblies of mold designs.
