In the latest snapshot, I cannot move items around in the player inventory (including pulling stacks from the creative inventory).
How to reproduce:
Open the inventory
Click an itemstack
--> item not picked up

Sure, I edited that into the description. It's pretty simple. You want video, too?
Can't reproduce with those steps. Do you perhaps have touchscreen mode enabled?

Cannot reproduce on Windows 8.1 either.

Touchscreen mode is indeed the culprit. I did not even know this was a thing and having it be on by default is quite frustrating (especially as I don't have a touchscreen).
Provide a step by step reprocuction guide please?
