[X2Go-User] Connection failed xhost: unable to open display "" on Windows 7 with x2goclient-3.99.3.0-pre3

Hi,

I have this problem with all newer versions of x2go on Windows 7. I have been trying to use a newer version than 3.01-4, but every time I do, I sooner or later get this error. Then I revert back to the old version and then it works flawlessly. Then, after some time, I wish to give a newer version a try and end up with the same problem, unable to use x2goclient. The strange thing is that I now used 3.99.3.0 for a week or so, without problems, but now I am stuck again, it just popped up out of nowhere. How can I fix this? It seems the vcxsrv is might not be started, but when starting it manually, it does not make a difference at all.

Thanks,

Markus
