inventory

Im having a bug on the crafting table and on the inventory

...:*What is supposed to happen is that if I click on an item, I am supposed to automatically drag it without left clicking all the time, and if I right click, one of the stack of the item is put on a slot.

What happened is that when I clicked an item, I couldn't automatically have it on the cursor, so I have to drag the item by left clicking all the time till I get to the spot. And I can't place items, from my stack, one by one in the slots.
