Izawa has updated all his theme for 10.2.4 compatibility. I emailed him and asked what changed, but I have not received a response yet.

I tried some of my themes and they seem to work fine. The only trouble was that ThemeChanger had an old Aqua backup that it applied when I switched back and forth between themes.
So my recommendation is that you remove it (from the menu in themechanger) before you start switching themes.

Does any one know if the BootX file changed in 10.2.4?? I think I'm going to update my themes and remove the BootX file, just to make sure the themes wont cause any serious damage in the future.
