For some reason my F2 and F3 keys aren't working. They worked fine and then all of a sudden they didn't. So now I can't take screenshots or get coords. I sure would appreciate it if someone could help me. Thanks.
You can always use the command /getpos to get your coordinates, as well as using other methods of screenshots, such as printscreen or "snipping tool" as long as you get your full game window.
Do you happen to have the optifine preview for 1.7.2 installed? That might explain your screenshot problem.
No, I haven't installed optifine for 1.7.2 yet. I had it for 1.6.4 but not the new one. This is just so typical of my computer experience - things work and then they don't for no apparent reason. I'm starting to think the gremlins might be at work here.
