Minecraft crashes when I leave the "Creative inventory". It happens on both single player and multiplayer modes.
To reacreate the bug, simply create a world in creative mode, open the inventory, then close it. Minecraft will then crash! The report says "Minecraft has stopped running because it encountered a problem; Updating screen events".
This may be similar to earlier big reports for version 1.4.2 and earlier, resolved in version 1.4.3. But this problem is occuring in version 1.4.4.
