I can open an Excel file that has been attached as a file in OneNote 2013 running on a Windows 7 system but, when I click on Enable Editing to allow editing, I get a popup message that says it can't find the file. The file is displayed but it can't find when I click "Enable Editing." Has any one figured out how to get past this? It usually occurs only if I have one or more other spreadsheets open. It is not always the same spreadsheet in the bunch I want to open.
Sometimes shutting OneNote down and restarting it helps. Most times it doesn't.
