When I first reported this problem I was told it was because my wacom tablet was old, my computer was out of date etc. Now I have a brand new computer and a brand new wacom tablet and still if I am not careful my clone tool goes automatically alined when I select an area to be cloned the box ticks itself I can see it happen if I accidentally tap the pen twice in quick succession to the tablet when making a selection. Now this may be okay for you younger people with your steady as a rock hands but no matter how careful I am this is still happening by accident to me. Some may see it as a feature me I would just like to be able to turn it off.
