There's also no way of using any of the usual methods known from Linux (Alt+Mouse or any of the Gnome/KDE keyboard shortcuts). Idea of my message was that such ways _do_ exist. Try "g alt+mouse move ms windows" (Opera-style way of fast search) and you'll find plenty of small utilites that implement such functionality
- information how to implement it on your own ( z.B. http://stackoverflow.com/questions/3100711/move-a-window-on-keypress-mouse-l... ).
Currently I'm using "MoveInactiveWin.exe" utility ( IIRC I've downloaded it here: www.donationcoder.com/Software/Skrommel/ ) but may be you won't trust this piece of obfuscated code and want smth better ( z.B. https://code.google.com/p/altdrag/ ). I agree that this is a _workaround_ (as we still don't have the thing that's working out-of-the-box) and real solution would be to write and include such code in vcxsrv or implement some helper program (with this function) as a part of x2go distribution.
