This problem has affected me for a long time. I use Dreamweaver 8 Manage Sites to synchronize the local file and remote file of the site. Although I save FTP login and password every time, when Dreamweaver is closed, next time, re-open it again, FTP login and password is lost! Google the solution, find it is caused by damn IE7, to solve the problem, quickly download 8.0.2 Updater.
