I googled and came up empty. Anyone have experience with ajaxterm? Given my login name is "jae", just as on this site, this inability to enter "j" kills ajaxterm for my purposes. It looked so good. Damn.
EDIT: Dammit, it was just Firemacs with its idiotic keybindings. Removed all the ones which are really "emacsy", and all's fine now. And the disappearing window was due to me changing the rows/columns, which requires a restart (of a daemon that doesn't show up in pstree, weird).
