This started happening to my wife when playing on our small family server (over a LAN, but we use the JAR server). The game keeps crashing every time she enters a nether portal from the overworld. I, on the other hand, can freely move back and forth between the Nether and the overworld with no problems. Our Minecraft installations are identical, but I run the JAR server on my machine (along with the client).
This bug affects my Mincraft installation on two different Windows 7 64 bit computers. It doesn't matter if we use a clean update or not. The version of Java being used doesn't matter. Other Java programs do not have this problem. It first appeared for us when we upgraded to 1.3.1 (we don't install the snapshots) and has persisted through 1.4.2 at the time of this writing. The memory used by the inactive, unclosable javaw.exe instances is not freed up until the user either logs out or restarts. This memory use kills my system that has only 4MB of ram.
