I'm using Real VNC Enterprise Edition with Windows 7 and no problems. The only minor issue that RealVNC does not restore the Windows 7 wallpaper changer once you log out remotely of the computer. It just restores the current wallpaper but the changer feature is no longer active. The only work around so far is not do disable the wallpaper when login remotely. Other then that I have no issues. I have tried other remote logins but prefer Real VNC.
