I just uploaded Beta 7e. It fixes a couple more bugs, and includes an experiment in swapping the logo files on the fly.
Besides the program itself, the ZIP file contains a logo file called SSLogo256d.png. If you put this file in the same folder as MA3, when the program is running you can use the L key to swap between this file and the default texture.
