Hi. I have a problem. I want to open one TB for multiplayer and one for singleplayer. I'm using a Macbook. Whenever I click the icon for TB the second time, it just brings the window that's already open to the front.

Is there any way for me to do this?

Uhh, I have a mac, and I would say, there probably is a way. I haven't been able to find out how, but I stopped trying a long time ago.
Possibly, you could have an old toribash version and a new one in different places in your HD and start them up separately. Never tried that.
Though, you have to be careful. If you get caught on multiplayer using both accounts, you could get in big trouble.
Macfag, out.

Yeah, I know about double-clienting. I just want to mess around in single player while I wait in the extremely crap-tastic Judo lines.

Also, I'll try the thing with the different versions.

Goodluck. I haven't tried it, so it may work.

I think that the finder doesn't allow that.
You can trick it though:

Enter the Toribash folder, and copy Toribash application to Toribash1
(You don't need to copy the entire Toribash folder, just the Toribash application (It has the Toribash icon)
