WebWindow about: commands and Java script equivalent list.
If you have Internet Explorer 9 or a later version installed then some about: commands will not work in frames and/or iFrames, unless you are in IE 7 mode.
WebWindow supports extra Javascript code from version 3.18.0045, but not in frames, iFrames and sub-frames.
WebWindow supports extra Javascript code in frames and iFrames from version 3.20.0047, unless ww_extraJS_inFrames is disabled in the options window.

You should check if the extra Javascript code works in a frame/iFrame first and if it fails then try to load the about: command in the frame.
