This should do it...
Update: (b1.1.5)
-Fixed another bug with backdrop saving. Statusbox color/alpha was not what was chosen in the designer.
-Another side fix of the main fix is, colors of the statusbox also save now for the default backgrounds as well. Before they were ignored unless you chose a background.
Problem was when I added the better alpha blending I should have written 2 separate functions for saving and redrawing the smartdials, hehe. Instead I made a mess of checks to get away with one and I confused myself. Fixed it though and split it into 2 functions.
Thanks for reporting bugs by the way. It's good to get these bigger ones taken care of. I had to change a lot around when I changed alpha, because my old method would have frozen up the program for a couple mins while it redrew all the buttons each time you change a color or setting, hehe.
Throughout these changes though, the .skin files will still work. It was saving settings correctly all along, it was just the images, so easy to load back up and re-save.
