I've posted this question on the Finale forum and there are a few of us that have this problem. I've also raised the question to the tech support at Finale, but that seems to be a dead end. The problem is only with 2006C, and it happened from the very first note played back. Even the scrolling cursor seems to be out of sync.
There is a hesitation and "pop" at the beginning of the playback and at the end of the piece it scrolls the last bar again, sometimes all of the bar and sometimes only part of the bar. There are time that it doesn't do it but most of the time it does hesitate and "pop" (for want of a better word). It is really annoying. I'm sorry to take up space at this forum but I don't know where else to go. I thought maybe some of you, who use Finale might have had this esperience. Thanks
