Hello,
I haven't had a chance to test the skin in 4.3.2 yet. - This sounds like a HouseMenu problem. - So you have placed in the XML file ShowAdmin as False for the HouseMenu? and the admin menu still displays?
There's nothing I can suggest for this as the HouseMenu is not created by me. - You will need to get in touch with the House of Nuke -
www.houseofnuke.com and see if they can offer any solutions.
You are probably right in that 4.3.x is introducing a different implementation of the code which is affecting the HouseMenu.
Let us know how you get on,
Thanks,
