Does this happen to anyone else? This has happened to me at work (before my
internship ended) and now it has happened at home. When I highlight an
entire word, line, sentence, etc. and press the backspace key, nothing
happens. Everything stays, except I lose my highlighting. I'm left with
either having to delete each individual letter (which still works with the
backspace key) or using the delete key (as opposed to insert) to delete
highlighted material.

So again, does this happen to anyone else? And how can I get rid of it?
It's been the second day.
