Ira and all Some strange event happened to me when upgrading to 2.30x. Prehistoric: I have used Event REFN very much adding a number into the Misc data field. The No could look like this: 2F3A4C 5A6A. No other data was set in the General part of the event. On the source I've marked up a general source which I often quote. Sometime I also write a note. Now: Having installed 2.30x without troubles I started with a Rebuild Keyfields , UPPER PART check for all except Standard Events; LOWER PART check in Autosort dates and Correct Living flags 100 as my first task and now the task completely stopped by individual 453 - I could see a No like the abovementioned and the sec. part of the xxxx:453. So I had to shut down CFT ! Start CFT again and load the db and go to indv. 453. Looking at this person I could see that the NUMBER of the REFN - originated into the Misc now was placed into the DATE field! - which must have stopped the rebuild routine. After having corrected 15 of this kind I got through the problems. A comment: the fault was in a range from 453 to about 500 (Ind.no) and loaded into the db long time ago, probably in 2.26x. Later I installed 2.27x and continued entering data to the db. I also installed 2.29x but did not use it for entering data - just for looking and checking. I always end a version ie 2.26x with a Rebuild Keyfields and a report and I always start a new version with the very same routine. Have you any idea what could have caused this? Rgds Rolf
