[X2go-User] x2go client errors under Windows 7

Does anyone running X2go client under windows 7? I am getting two issues. One is I have to manually launch Xming Server, which is not a big deal. Another is every time after connected I always got two error dialogs, "Can't read host rsa key:C:\Program Files\x2goclient\etc\ssh_host_rsa_key.pub", then another "Unable to read:.pub". They don't prevent me from using the client but very annoying and always need two extra clicks to close them. Is there any way to fix this? Thanks! Jian
