Hey Mikes :-)

Thanks for your replies. We resolved the problem by recommending the x2go client version 4.0.2.1 to our users which includes a sufficiently old Vcxsrv. We are fine with this solution.
Please keep this upstream-bug in vcxsrv in mind for the case more applications show the problem and replicated bug reports are created.

Thanks for your efforts on the x2go-software!
Martin

Hi Martin,

This is a bug that I do intend to fix when I get a chance, even if it means fixing the bug in the VcXsrv code. However, I am not an expert at C, and I probably will not fix this anytime soon. (Patches from others are welcome.)

However, in the meantime, you can follow this workaround:
1. Install VcXsrv (VcXsrv-xp) 1.14.3.2 and remember where you installed it.
2. Configure X2Go Client for Windows to use that vcxsrv.exe as an external X server: Options -> Settings -> X-Server settings

If you have a large number of users or machines that need these settings, you can save the settings a registry key that can be exported and imported per-user-account and per-machine. The reg key
is:
[HKEY_CURRENT_USER\Software\Obviously Nice\x2goclient\settings]
