Can't add files to upload queue

Recently reinstalled windows (Win 7 x64). Now when I fire up SmartFTP it connect to the server, lists all the files and lets me download. However, I simply cannot add anything to the upload queue.

I've installed on the same machine and that is working just fine. Turned firewall off, still the same.

I am having the same problem with Windows 7 Professional 64 bit since I upgraded to 4.0.1164.0. It worked fine on the previous build. When I drag a file from my desktop to the folder on the website it displays "+ Copy to [foldername]", but nothing happens.

yikes, anyone got a link to an older version ?

Bug confirmed. Fix coming in 1h.

thanks
