When selling items you get an option of selecting between one and the maximum figure. However, if you've never sold an item before you probably don't know its worth, and as such have to drag it into the box to find that out.
This is fine and dandy, but if you decide it's not worth selling then there's no way to deselect the item (cannot drag it back out or drag something back on top to override your selection). A way to do this would be great - otherwise you need to click out of the selling screen and back into it.
Thanks!
