What I expected to happen was that I could "shift-click" items into and out of chests, player inventories, creative mode inventories, crafting tables, furnaces, and various mod items.

What actually happened was I ended up only being able to click and drag an item out from any of the places stated above.

Steps to Reproduce (Remember, this bug is on my computer only, as far as I know):
1. Go into creative mode
2. Take out any item from any slot in the creative mode inventory
OR
1. Go into a survival world
2. Try putting items into chests or take items out of chests
