When double-clicked to open from the Mac desktop, Windows documents whose default "open with" application (as seen in the Mac "Get Info" panel) is one version do not open with the later version--even after they have been saved (overwritten) as the newer version within Windows. I do not know if the default application was specifically set in the "Get Info" panel or just defaulted to that on its own. Other than manually changing each document's default application on the Mac side, is there another way to make the Windows-saved default stick? The new version's format is incompatible with the old version, so documents keep attempting to open with the old version but fail. The application icon and extension are not distinguishable between versions, so one must remember which ones have been set to the old version and/or reset to the new version, or always open from the Windows desktop--not (usually) an efficient workflow and certainly defeats any use of Coherence mode. Thanks for any help. Note: Choosing the "Change All" button in the "Get Info" panel is not an option... I cannot change all existing files at this time as there may still be need to use the older version of the Windows application.
