Hello This is my first post to this list. I recently upgraded to Openbook 8. I am using a machine with Windows 7 64bit. I have experienced things that never happened in previous versions. When I try to close Openbook after using it for whatever purpose I frequently have my computer lock up on me. At other times it locks the computer in a "Switching" mode where I cannot close any open applications or use them. I can Tab or Alt-Tab through the applications but they cannot be used or closed. I notified FS about this and they had no answer. I hope someone does have some answers. On another matter, I have found that, "buck Scan" is doing a worse job of identifying bills than in version 7. Has anyone had the same experience? Thanks, in advance, for any help. Wayne
