I think this is probably a simple one, but I'm having problems finding the file I need to edit for the Admin loading page. I've been able to change the loading image but I'd also like to change the background colour too.
Can anyone please point me in the right direction??
Note that you can use LeftAndMain::set_loading_image('themes/MyTheme/images/CMSLoading.gif'); to change the loading image and a LeftAndMain Decorator to Decorate LeftAndMain without touching corefiles.
