But I notice that it does depend on how many lines of the xterm window are on the screen. If I move the window partially off the screen the problem persists until < 158 columns remain on the screen. As soon as 157 or less columns are on the screen, the problem goes away, even though the xterm window is still larger. > Does this happen in remote xterms, or just the local? > It also happens if I log into a remote host then run a remote xterm back to this display. -jr [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (FreeBSD) iD8DBQFHPLJAls33urr0k4kRAp3zAJ4o5z7v/DHnubaC7Boe2TxDtnyJCgCgolB4 imQ/wxNL3ZwRzIMggiH8HoU= =PhLI -----END PGP SIGNATURE-----
