Try turning off Cell Drag and Drop (in Tools/Options/Edit), BUT this
is a fantastic feature, especially for quickly navigating to the end
of data (in any direction). It jumps to the end of your document if it
does not encounter any content on the way in exactly the same way as
[End] followed by an arrow key.
Note that turning off Cell Drag and Drop does not turn off the End +
arrow key navigation system.
