#9 Can't use "self" as global var with MSIE

[Rich K]

We set up "self" to be a global variable so we can access it within eval strings in formulas. (not pretty, but it makes the api a lot less quote-ish). since MSIE already has "self" as an alias for "top", it collides with this usage. Need to think through how to provide the above behavior without this. Could rename "self", but that would be onerous and not look as good.
