Minecraft Forums

Lately I've been having this weird issue with Minecraft. Whenever I'm waiting for a game to start or i'm cooking meat/ I want to browse the web/ chat with friends while I'm waiting. So sometimes I spend maybe 30 seconds or a minute doing something else waiting for whatever is happening on Minecraft, and when I'm done browsing or chatting and return to Minecraft, I get a message saying that it isn't responding. I close the window and program and I'm back at the launcher. This is getting really annoying since I like to play Hunger Games and TNT Run and I end of getting killed because of this problem. Any thoughts on how to fix? I use Windows 8.1 BTW.
