[X2Go-User] Black screen for existing session

[Karel]

 Last week or two I used my x2go session only from my home computer and at
every evening it connected without problems. At sunday evening I updated
and restarted my server side also (and reconnected to this new session at
sunday evening without problems).
 Today morning I tried again after long time from my work computer, this
was updated at friday and i also installed PyHoca client there. PyHoca
client connected but cannot resume my session left suspended at home last
evening. I can only create new session and kill the old one. So I did and
used this new session until evening. Now at home I can not resume this
session created at work. Again I can create a new one and kill another if
I want.
 So the problem is: I can create a session and reconnect to it only at one
computer but cannot resume session created at another computer. I am only
using PyHoca at both places at the moment and have no third place to try.

 Here at home is Windows7 at client side and information from client
(PyHoca-GUI 0.4.0.2) is at the moment:
