I recently installed the Adobe Acrobat program. but have not yet tried to use it. Tonight for the first time since that installation I tried creating Family Group Sheets and a pedigree chart within FO in pdf format. The pdf files are not opening as usual, and when I go to Adobe Acrobat and try to open the saved pdf files from FO, it says there is an error in opening the file. In addition FO tries to open the pdf files to Word Pad instead of Adobe Acrobat. The Acrobat program uninstalled my earlier Adobe Acrobat Reader before the Adobe Acrobat program would install. Do any of the experts have an idea of what has gone wrong and how to get FO to again automatically open the PDF files? Margaret Scheffler
