I have experienced the following wrong behavior on "Worksheet window splitter".
By splitting to control two distant parts of the worksheet at the same time, if I scroll or click on an empty area, the behavior is correct and I keep the view on both sides. But if I click on an element of a part (image, mathematical area etc...) then the other part is also brought into the same area.
It also creates a new file named "NewWorksheet_443.sm"
