I have no problem whatsoever with that setup. Use r1256-1257..
I reported seeing the same issue initially but since then I have been unable to reproduce it, I only own a couple of CG games though so if I'm honest I've not really used it too much since then.
The network issue is something I have experience regularly, I may not be able to test real time but certainly could test, I'm in the UK so timing may be easier.....
