z-Tree.exe

• z-Tree works almost perfectly. Sometimes the screen redraws fail, so the layout of the program on the screen is garbled. This can always be fixed by collapsing and expanding the program.

• All the programming functions seem to work very well.

• If you kill a z-Tree you sometimes have to wait for a minute before a new z-Tree can access the network again (the same problem occurs also under Microsoft operating systems).

• z-Tree and also z-Leaf have a funny way to determine their IP address. They try to get their hostname and then look up reversely the corresponding IP address with the help of the DNS mechanism. Thus, your hostname must have a corresponding DNS entry, or an entry in /etc/hosts

  If this reverse looking up of IP addresses fails, z-Tree and z-Leaf will self-diagnose a missing IP address (which is misleading, since the machine usually has an IP address and a working connection to the internet).
