Ug, Minecraft updated today and now it's crashing frequently. I reduced my view distance a notch and that helped, but its only brought the problem from "crashes after a few seconds" to "crashes after a few minutes."
Was this the update to 1.2.5?
I wouldn't touch any of the updates really until the became official updates like 1.1, 1.2, 1.3 etc...Just to avoid all the bugs creeping around in the test batches, then again that's why they're released like that, to get rid of those bugs
