Can the System Buttons be replaced, graphically? Currently I'm not using any of the System Buttons (B0 - b7) because I've added a bunch of Custom Buttons. Now I would like to add specific station logos for the favorite channel buttons but I've exhausted the number of buttons allowed in the registry (31). I tried replacing the files B0.btn through B7.btn with station logos and retaining the same file names (B0.btn - B7.btn) and I was able to lay them out using the MXOP. But when I tried downloading the Operating Program, I got an error and it crashed.
Is there something that I can do regarding the size of the buttons (the logo sizes are different than the original System Buttons) or is there some data that I can change using MS Access to make this work?

Any of the buttons that come up saying they "can't be deleted"... well, can't be deleted. I think there's a couple in the B0-7 range that can be customized though.
