The left/right scroll bar is difficult to find because it is not visible until you first scroll to the bottom. After scrolling to the right, you have to scroll back up to the transaction you want to edit which is now at least partially obscured on the left hand side from having scrolled to the right. You may need to note the values of the transaction to identify the correct one for editing.
These types of bugs should not exist in commercial software and is really disappointing after having such a high quality product for so many years.
