NX client and Lion

I have all sort of problems with screen resolution with the beta nxplayer and Lion.
Plus, cut and paste does not work

What seems to work is opennx

http://opennx.net/

using
http://sourceforge.net/projects/opennx/files/opennx/CI/OpenNX-0.16.0.649.dmg/download

It will give you a wrong keyboard map. On the server, edit

/usr/NX/ets/node.cfg

to add

AgentExtraOptions = "-kb"


and restart with nxserver --restart
