Hey Alessio, I'm sorry but I have to bother you again with my "length-problem" when importing from an old xMM-database. The new checkbox on the import-dialog Do not calculate length, copy only from old database doesn't work as it should be. When I check this checkbox everything is as I reported in this thread: http://www.binaryworks.it/forum/topic.asp?TOPIC_ID=1614 But when I leave the checkbox unchecked it works correctly and my length format hh:mm is converted in minutes only. So it would be nice if you could take a look at this function again. Thx!!
