What's the proper way to document and report the black screen issue? I think a lot of people call this a "crash", and it's what I'm getting every session now, after 5-15 minutes of play, since the Halloween update. I'm on the verge of just quitting it altogether.

After extensive testing in single player and online, I can report that this does not work at all. I still get the black screen every few minutes when not in Normal rendering mode.

How to use: Open minecraft.jar in your favorite archive program such as 7zip and replace the existing fz.class with this one. Also be sure to delete the MOJANG files located in /META-INF - leave the Manifest file!

For the interested; The diff in the code is the following:

   public ex b(ic paramic) {
+    try {
     return a(paramic.getClass());
+    } catch (Exception e) {
+    }
+    return null;
   }

Not quite spectacular, maybe slight sloppiness from Notch? :smile.gif:

Is it the same problem, or different?
