I released AutoCAD 2005 to my user base about 2 weeks ago. A user says he is running into a problem when doing a plot and writing an Adobe .pdf file. About 1/3 of the time AutoCAD hangs and he has to kill it off and restart. This problem never occurred with AutoCAD 2004. He is using an older verison of Adobe (5.0). Anyone experiencing this or know what might be the problem? Thanks, JPM
