According to W3C DOM Level-1 specs, offsetParent is not a DOM object property. I 
couldn't find it in level-2, or JavaScript either. Hakan, where does it come 
from?

[Håkan Nilsson]

Sorry! :/ Got my IE5 and Mozilla mixed up (offserParent is a IE-Specific 
property) it isnt a part of Mozilla, DOM or JS (but somehow it seems to break 
M14)

A found "the bug" when I was trying to get my primitive DOM-analyze-page to 
work with IE5 and M14 (it was working fine with M12)
http://www.algonet.se/~delphi/mozilla/document_view.html
http://www.algonet.se/~delphi/mozilla/document_view2.html

I will try to break it down further and check back when I find the "true" bug...
However M14 still crashes when calling (document.documentElement.offsetParent) 
and that is no good :/

[e-mail] - although we aren't implementing IE-specific stuff, 
is Mozilla still crashing when presented with this?

I'm unable to reproduce this any more, I know I at least tried to fix this but I
don't remember when, marking FIXED, please reopen if it's still crashing.
