Hi - I've got this very very irritating UI bug that means when I click my mouse on items in the UI, like the inventory, at times it selects the game world.

It make thieving very annoying, it makes crafting very annoying, actually it basically makes everything annoying because even in combat i'll be looking at the inventory or something and it will click out a move behind the UI.

Running windows 10, both full screen and fake fullscreen. My mouse acceleration is off in windows (its the 'smooth' mouse checkbox under the windows settings)

Please help?
