Title says it all. when i try to join it freezes up and i have to forcequit. :/ something is up...admin time!
I've found the hang is actually OptiFine. Whenever the session servers are down, game hard freezes due to OptiFine. I actually turned off Optifine last time servers were down due to the issue...
I don't have optifine installed at all and I couldn't get in to certain servers. I could log into 7 and 9 and I think I got on utopia but the others I tried I got an error message. I didn't know what was going on.
Thats due to mojang server issues. I was commenting on the fact that when you get that error message, if you have Optifine it will hard freeze minecraft and you cant even see the error message or button, and you have to force kill it.
