After just a couple of minutes play, Minecraft is using all free RAM and Windows is paging to disk like crazy!
Changing graphics from Vibrant Visuals to Simple and reducing render distance has no effect on the use of memory. Starting from fresh re-boot and loading existing game has no effect on the use of memory. Just loading the game and then doing nothing has no effect on memory use; in all instances the memory use increases until the system is exhausted.
After a short time the game becomes unplayable - but closing the game and exiting to Windows does not reduce the memory back to its pre-game levels - memory remains in use and the background music continues to play.
