Dear Vicky, dear All, The newest release included a change for the maximum length of ResonanceGroup.details, from 254 to 4000 characters. It now appears that the backwards compatibility was not correct, so that the code may have ignored the old ResonanceGroup.details. The problem has been fixed, and an update has been posted to the update server. If you use ResonanceGroup.details for anything, and you have been working over the past week or so, I would recommend that you check if you have lost the data in ResonanceGroup.details and either re-set them or go back to an earlier back-up. The problem will not appear again once you have got the latest update. I apologise for the mistake. Yours, Rasmus --------------------------------------------------------------------------- Dr. Rasmus H.
