5. I simply set a background for the mainscreen, exit Options, saving settings, iPT does the "Loading" screen and I eventually see the background added to the configuration that I had before, including still with wallpaper and static bars. In other words, everything is visible. If I exit iPT and re-launch the executable, though, that's when the wallpaper or the static bars disappear. So, the automatic disabling of them when choosing a mainscreen background doesn't happen or go into effect until the next time that iPT is run.
6. Oh, I see. I had thought that I was switching the focus to a different icon, not moving the icon to a new position. I really haven't played much at all with editing icons. Nevermind then; my misunderstanding.
BTW, I just now fixed and tweaked the two transparent bubbles. Please re-download. Don't worry that they look all white. They'll look right in iPT.
