Quick post this time - lately I've come across this obscure error in Javascript with Internet Explorer 9 whenever I tried to run a jQuery ligthbox script:

appendChildOriginal(element);



jscript debugger

breaking on jscript runtime error - invalid calling object

after tearing my hair out and "researching" the problem on Google, I came across this obscure solution:

IE:  Tools->Options Advanced Settings "Reset"

(found here: "Microsoft J")

Seems that all that is needed to fix the problem is resetting the Internet Explorer settings fixes the problem.

A translation of the line above is as follows:

In Internet Explorer 9, Open the "Internet Options" either from the Tools menu (hit ALT to make the menu appear) or the "Cog" icon drop down.

Go to the Advanced Tab, and hit the "Reset..." button.  On the dialog that pops up, hit "Reset" again.

That's it. problem solved.  No need to reinstall IE 9.
