Had to split a stack and notice the new split stack option pop-up. Then I right clicked on another stack in another split stack option popped up and another and another. It seems that it doesn't recognize that there is already a dialogue box opened.
Just a bit of feedback on this new split stack pop up, it just seems a bit too large and not as efficient as the old split stack feature. I really didn't think there was anything wrong with the old way of splitting stacks. If you want to split a stack in half, you would simply right-click and if you wanted to split the stack to a specific size, you would right click and hold but that's where I find lies the problem. If you move the mouse out of the dialogue box, it would disappear and you'd have to start over.
So why not eliminate the option to close the box until you release the right mouse button. This way when you right click and hold, you can specify the amount on the stack by moving your mouse around and when you're happy with the stack size, you would simply release the right mouse. As well as long as you hold down the right mouse button, the split stack dialogue box won't disappear when you drag your mouse outside the box. This would work a lot better than it previously did.
Just thought I'd throw that in there.
