When I try to launch 1.7.2 (latest) or 1.6.4, it crashes. It used to work with 1.6.4 and 1.7.2. (Yet, 1.5.2 and 1.4.7 work though.) No changes made to machine that I know about. Drivers are up to date.
Steps to Reproduce:
1. try to launch 1.7.2 minecraft.
2. See the following:
java.lang.NullPointerException: Initializing game
I do not know if "No OpenGL context found in the current thread." is good or bad.
