As you may have learned, there is a new version of the XMLmind XML Editor (version 8.0.0). While it does load XLingPaper documents, it breaks the “Convert interlinear line to wrd elements” command (the Shift-F10 one). If you are keying interlinear text, this is an extremely useful command. XMLmind assures me that there will be a fix for this in version 8.1 of the XMLmind XML Editor. So please wait.
If you have already upgraded and need this command, I recommend you uninstall version 8.0.0 and reinstall your version 7 one. If you need to download the latest version 7, these can be found at the following links:
