I forgot a debugger statement in the DFFS_frontend_min.js file in v22.214.171.124 posted yesterday. If you have installed this version you must update the file /SPJS/DFFS/js/DFFS_frontend_min.js to fix this issue.
You find the compete change log here, and the updated files in the download section of the user manual.
Post comments below, but use the form if you have questions or you think you have found a bug.
Sorry for the inconvenience!
