Hi everyone,
I'd like to notice that this bug is fixed in preview/4.0.3.0-pre01: http://code.x2go.org/releases/binary-win32/x2goclient/previews/4.0.3.0/x2goc...
but it still persists in release/4.0.3.0: http://code.x2go.org/releases/binary-win32/x2goclient/releases/4.0.3.0-20141...
Please do apply the fix to the release version.
Best regards, Dmitry Mikhailov
