We have always expierenced that the API "hangs" when trying to use the UseCompression in our interfaces to the VC server.
objConn.ConnectionType = Connection.ConnectionT.Remote
objConn.Port = 16444
objConn.TimeOut = 3600
'objConn.UseCompression = True
objConn.Address = ServerAddress()
objConn.UserName = UserName()
objConn.PassWord = Password()
With the installation of version 37 we saw similar behaviour if the compression option on the Server connection dialog in the VC client was enabled. The connection bar (bottom right) got to about 20% and did not progress further. Remove the "compression" option in the connection setup and everything works. Is there a switch/button somewhere I need to turn -on? On version 11 the feature worked fine and there was a noticable start-up difference on the client.
