No. But I did find a way to get it to work. I got to the persons record by opening the event list, double clicking on the event to bring up the event window, then finally clicking the go button to end up at the persons event. If I delete the offending event then add the new one without closing all of the intermediate windows, the error occurs as discribed. If I close out all of the windows except the one persons record (can't close it anyway) first, then make the same changes, no problem. I suggest not adding or deleting data with multiple windows open. I have in the past had problems when I has cleaning up my place library. I could not ever understand what had happened. Could have had multiple windows open during this process. Is this a known bug? I hope to hear what UFTEngineering has to say.
