hmm - I have essentially the reverse (I might be able to reproduce this)

vile's using the api for carets, though there's an additional complication
in vile because it's doing polling, e.g., to provide usable screen updates
when running a shell command, as well as to sense whether a key is pressed.
(It's "usable" but not perfect since I get screen debris due to switching
modes).

Notepad doesn't do that - I'm not that familiar with Mined to guess.
