Recently I upgraded to the newest version of Minecraft only to find out that it's not compatible with a few of my favorite mods that I use. So I got my backup 1.5.2 jar, and used a custom launcher (Magic Launcher), and everything works fine.
The only issue is that when I go to the screen there is a nagging message saying that 1.6.2 is available for download. Can I get rid of it somehow or what?
