Our use of ESRI software requires frequent use of the export to PDF function in ArcMap. Recently, whenever we export to PDF in ArcMap 10.1 (service pack 1- build 10.1.1.3143) the resulting PDF has jumbled labels (whether annotation or labels). It may be significant that this problem has only occurred after many of our source folders were moved locations within the same drive on the same server (and renamed in the process - all broken sources were repaired). Has anyone else had this issue and/or know a resolution? Any input would be appreciated.
