By the way, the controller lag issues made sense and I was able to fix them, but I'm completely lost on any other bugs with the themes manager, such as images not loading, etc. Do keep in mind that images will only show up for themes that are available and have been approved on the server; if "Latest Version Available" is listed as "Unknown", then the theme hasn't been uploaded yet and nothing will show up for it. You'll be able to uninstall it or apply it, but that's about it. If it's taking forever to load up the themes manager, it's probably some sort of a connectivity issue.
