This may happen if redisplay traps e.g. during tool-bar update with input blocked. */ while (INPUT_BLOCKED_P) UNBLOCK_INPUT; return Fthrow (Qtop_level, Qnil); } This approach of unblocking input appears completely useless to me, since unwinding the stack includes restoration of interrupt_input_blocked. -- David Kastrup, Kriemhildstr. 15, 44793 Bochum
