Whenever I am transfering items to or from a chest most of the time it doesn't actually take effect. When I exit the chest screen all my items go back to how they were even if I am holding them. If I stick it straight into my item bar it will disappear shortly after leaving the chest. This is extremely irritating and makes the game near impossible to play. It is not lag. I'm playing singleplayer and I run at at least 40+fps at all moments. I'm using optifine. I'm also experiencing the double click problem all of which just appeared with the 1.3.2 update since none of the issues were present when I was running version 1.2.5.
A little bit more information here: I also play minecraft on my macbook air and I sometimes (rarely) have the double click problem when I hit low fps, but I never experience the chest bug. My PC is far more powerful than my macbook which usually runs around 30fps, so that shows that the problem is not necessarily related to performance. Also, they use the same wireless network and both are playing singleplayer with the optifine mod.
Chests are not functioning properly
