I have to hold items

Hello,

If I want to put an item from my inventory to another slot, I have to hold it instead of clicking it once and having the item. I also can't put an item away by clicking another item in the creative blockinventory, but have to go to the X in the normal inventory. I wanted to take a video of it, but now the game keeps crashing. I hope it is getting away with time or that I can do some simple things. Oh, I already put my laptop on and off, didn't work, I also reïnstalled the game, but also that didn't work. I have this now for 3 days. I hope somebody can help me. And sorry for my bad English. If you are not sure what I mean, just ask. This was my bug, If i can call this a bug.

Ps. I hope the 1.13 update comes fast 🙂
