Of course it can happen, indeed it's pretty common. Any easy way to cause it is to use a non-default mode-line face (e.g., a border of size other than -1, or a different font), or include some fonts in the buffer that have a height different than the default font-size (e.g., just look at the HELLO buffer with `C-h h'). Emacs is generally quite flaky in this circumstance too. I avoid leaving my cursor in the last line because Emacs has a bad tendency to scroll/jump randomly when it's there. -Miles -- Do not taunt Happy Fun Ball.
