[X2Go-User] Copy and paste between systems stops working

[Lmhelp1]

Hello,

My question is about not being able to copy and paste strings between 
two systems via X2Go.
I have two systems which specifications are:
* on the one side, a Linux system:
- OS Debian (Buster)
- x2goserver (v.4.1.0.3-4)
- Openbox (v.3.6.1-8)
* on the other side, a Windows system:
- OS Windows (8.1 Pro)
- x2goclient (v.4.1.2.0-2018-06-22)

Here is the problem:
as long as I copy and paste strings from the Windows system to a console 
(xterm) in the Linux system, it works fine.
If I start, for example, "gvim foo.txt" which contains the string "foo", 
select "foo" with the mouse and try to paste it in a Gvim or a Notepad 
running on the Windows system, the string "foo" is not pasted in the 
Windows Gvim or Notepad.
And starting from this point, I cannot copy and paste anything between 
the two systems.
I have to close all the Windows in the Linux system, close the X2Go 
session and restart a new one to have copy and paste work again between 
the two systems.
And, as soon as I open a document with Gvim in the Linux system, and try 
to copy and paste strings to and from it, it malfunctions again.
Practically, it becomes very unhandy because I regularly need to copy 
and paste things that way between the two systems.

Can you help me solve that problem?
Thanks and best regards.
