I have several connections configured to use an RDP gateway. With 1.71 Beta 3, they worked properly. Since the upgrade to Beta 4 however when I try to connect I get an error stating that the host cannot be resolved. The hostname listed is the host name of the connection, not the RDP gateway.
If I run mstsc.exe with the same settings it works properly.
