Expression Web http://www.microsoft.com/expression/..._overview.aspx is an alternative, but it seems a pity to leave Dreamweaver.
Is it only the ftp that's causing a problem? I use the IE inbuilt ftp program which is perfectly adequate. Would this work with your proxy?
IE7 and IE8 have an ftp program built in which is perfectly suitable for uploading or downloading files singly or in batches although it lacks some other features provided by paid-for ftp programs. IE works in a strange way but is quite quick when you get used to it. IE needs ActiveX. You enter your domain name address with ftp instead of http like ftp://mydomain.com/ and ignore a window saying that it cannot display the webpage. You open "Page" in the top right IE menu bar and click "Open ftp site in Internet Explorer" (this only shows when you are trying to enter an ftp address), click OK in the popup, then right-click in the same place after the popup has disappeared which brings up a login popup and from there you get into your host server's directory file system.
Code downloaded to my PC will be deleted in due course.
WIN7; IE9, Firefox, Opera, Chrome and Safari for Windows; screen resolution usually 1366*768.
Also IE6 on W98 with 800*600 and IE8 on Vista 1440*900.
