In preparation for the upcoming release of X2Go Client 4.0.2.1, a new preview build (pre02 instead of pre01) of X2Go Client for Windows is available to download under: http://code.x2go.org/releases/binary-win32/x2goclient/previews/4.0.2.1/
It is based on commit 11e8f3a. http://code.x2go.org/gitweb?p=x2goclient.git;a=commit;h=11e8f3aeb3862e5ea4ee...
In contrast, the current 2014.07.02 nightly build is actually newer, it is based on commit f8464c4 ("Fix "fullscreen" mode on Windows 7 with several monitors.") I will release pre03 at some point, and it will contain that fix.
