Mojo WILL work with 3.01.19. Mojo will NOT properly display a .png files tranparent layer properly using 3.01.19. This does not mean that a .png file will look all messed up, it just means that it will not show like it should.
I have 3.01.19 installed on my hub and have used Darklight and am currently using Mojo and no problems. I just live without the reflections.
