The problem above is easy to workaround until the problem is fixed upstream (by overriding comint's `rear-nonsticky` property with your own). For the MacOS issue, I have no idea: maybe it'll be difficult to workaround, or maybe it's specific to unusual setups (really, I'm at pains to imagine how `cursor-intangible-mode` can cause the problems you describe, so I'd tend to suspect an interaction with some wild-west package doing dangerous things). > It also doesn=E2=80=99t seem to care about over-generous application of > =E2=80=98rear-nonsticky t.=20 It has its share of brokenness, don't worry ;-) Stefan
