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]
