Javascript Error in IE

[jimmynguyc]

I'm using the following:-
- ExtJS 2.2
- qWikiOffice 0.7.1
- IE7

This JS error appears on my IE7 whenever I close the Status Update box (lower right corner) after login manually before it dissapears on it's own.

The error was found on this line of code :-

if(G.getBoundingClientRect){
M=G.getBoundingClientRect(); <-------- here
N=C(document).getScroll();
return[M.left+N.left,M.top+N.top]
}


By the way, this error also appears when I test it on the qWiki's website demo.
