Using 2 Hosts at the same time

[mr kreps]

Hi!

I am using pca 12, my problem is as followed..

I want to use 2 pca-hosts at the same time.

I have one central PC which accepts a connection (via pca-host) from
the LAN. My second PC is in the LAN and I am connected to my central
PC via pca.

The central PC should wait for another connection. That means, I have
to open another host.

This doesen't work because I can only start one host at the same
time.
But in pca 10.5 it does. I can start 2 hosts in pca 10.5 at the same
time.

Why does that work in pca 10.5 and not in 12? Or what do I have to buy
to enable starting 2 hosts at the same time on one PC for pca 12?
