Well, not exactly that problem, but something similiar. I've got AmigaForever (3.9) running PowerIcons, and I can set the icons on my Workbench (RAM: WORK: SYSTEM: etc..) and they work with the new PNG icons. But when I reboot, they are back to the old glow icons, however, I can select the icon properties and it still shows the PowerIcons image inside of the box.. THAT is driving me nuts.
