As I read/remember it: Yes and no. The only promise made is that DOMSubtreeModified will eventually be fired after the DOM has been altered. It may be more often, or less often, than once per DOM method call, " at the implementation's discretion." I expect that most implementations will tend to favor the once-per-method interpretation, but that may not be convenient for the logic of some, and may be overkill for others which know these method calls are part of a higher-level operation. ______________________________________ Joe Kesselman / IBM Research
