The last few days on my Mac mini OS X 10.3.9 system, I've noticed all of my .dmg and .toast files keep getting icon changes. Every day, it's a new icon. The first thing that popped in my head was rebuild desktop, but that's an OS 9 thing. Any suggestions on how to get my icon association back to the default icon for my .dmg and .toast files? Is there some sort of hard drive utility that I can run to fix this?
