dont run in fullscreen, this will allow you to read wiki and play at same time.
I know that, but as I said in my main post it takes you out of the game. I know lots of people play games like Minecraft to get sucked in and it ruins the atmosphere if you have to alt-tab out and look at a wiki.
Or basically...having to rely on external guides to know how to even use something is really poor. This is a huge problem with the original Minecraft so I'm not blaming IC2 of course.
