Notepad++ scrolls beyond the EOF

If you update Notepad++ to version 7.0 or above, you'll now also have the option to enable this natively without plugins:

Go to Settings > Preferences > Editing, and check Enable scrolling beyond last line.

Therefore if you see this behaviour on a newer version of Notepad++ and don't want it, you might want to check if that setting is enabled.

This behavior should be controlled by the ScrollPastEOF plugin.

To remove it, open the Plugin Manager and switch to the Installed tab. Find the entry for ScrollPastEOF, select it and click Remove:

It was the Notepad# plugin which was causing this problem.

I reinstalled Notepad++, and when doing so, it said that the Notepad# plugin would be disabled because of an incompatibility. After doing this I can no longer scroll past the last line in the file.
