I recently started using the new 1.5 update. I went and downloaded optifine for 1.5 from the forum. I used MagicLauncher to install it and when I went on, my MC started to freeze up. I went into options and turned distance to normal as well as smooth lighting off and turned all animations off and changed everything to fast. I have 100+ FPS but then every few seconds my game will freeze for a second or two and the FPS will drop to 0 when it unfreezes, but then jumps back up to over 100 for a few seconds and then freezes again. Occasionally, it quit and say that Minecraft has run out of memory. I use MagicLauncher and the default texture pack. When I uninstall Optifine, my FPS goes down to less than 40 but doesn't freeze up. Could anybody help me figure out what the problem is?
EDIT: It also causes buttons and pressure plates to be activated, but will not be deactivated automatically. For example, a button will open the door, but it will not automatically close itself
