[FreeNX-kNX] Still getting cookie mismatch - freenx 0.4.3 and 0.4.4 on suse FreeNX-0.4.1-1.1.i586.rpm

Hi.

I'm trying to set up freenx to provide client access to kolab / kontact from
winxp workstations.

Have installed the FreeNX-0.4.1-1.1.i586.rpm, and NXSERVER - Version
1.4.0-04 OS (GPL) appears to be running ok.

Using the nx-client 1.5, I get "Cookie mismatch in the authentication data"

Looked around on the lists and forum, and saw that I needed to upgrade
freenx.  I've grabbed the tar.gz for 0.4.4, and got the error below.
Installed 0.4.3 over the top, and still get the same error.

Info: Proxy running in client mode with pid '2712'.
Info: Connecting to remote host '192.168.0.30:5000'.
Info: Connection to remote proxy '192.168.0.30:5000' established.

Info: Starting X protocol compression.
Warning: Cookie mismatch in the authentication data.
Info: End of session requested by remote proxy.

What should I try now? - and many apologies if I'm missing something really
obvious - linux newbie here...... :-(

Thanks
