I can no longer Export simple updated PDF files to a flash drive. Have always used the "Export" Option from "File", but it's not working now. Then tried the "Export as PDF" Option and it does not work either. Don't see any real difference with either option and the HELP routine is not helpful. The simple "Export" Option has exported just fine for two years, until recently. I must have inadvertently done something to prevent exporting. BUT WHAT ?
Your input will be helpful. Thank you. Edward
