Did you apply any patches, namely to simple.el? My definition of the function comes from d:\export\home\tmp\21.2\xemacs\lisp\simple.el and does not attempt to convert the `integer' ?\t (which it is not) into a character (which it already is). When I evaluate this: (int-char ?\t) I get that: Signaling: (wrong-type-argument integerp ?\t) int-char(?\t) eval((int-char ?\t)) eval-interactive((int-char ?\t)) eval-last-sexp(nil) call-interactively(eval-last-sexp) Try M-x find-function RET quoted-insert RET and see where it takes you. My suspision is that you get a bad definition of that function. Let's see whether I'm correct. Adrian Matthew> Do you need more?
