Running multiple instances on the same machine fails on the second instance

[GoogleCodeExporter]

What steps will reproduce the problem?
1. extract the zip file to two distinct locations
2. run the first instance
3. run the second instance

What is the expected output? What do you see instead?

Expected two copies of torchat running with two different users, but the second 
one fails to auto generate a user and shows 0000000000000000 in the title bar.

What version of the product are you using? On what operating system?

torchat-windows-0.9.9.458 on WinXP

Please provide any additional information below.

Without digging into the code, my guess would be something about two copies of 
Tor.exe stepping on eachother's toes. This may not be a supported scenario, but 
there's no real explanation of what's going wrong so at least a notification 
that it didn't work would be helpful

its not a supported scenario for the default configuration and it is mentioned 
on the project website.

It is possible for advanced users if you change a few port numbers in one of 
the installations, you will have to change torrc.txt and torchat.ini

There is also an old html document in the doc folder about this (its quite old 
and some of it might be outdated but might still give useful hints)
