Most icons on desktop are app logos instead of thumbnails reflecting their contents.
I came back to my computer today and found this problem. I rebooted, and some came back, but many are still generic app logos. Can someone explain what's going on and how to fix it? Thanks! BTW, I don't know if it's related, but sometimes the screen saver doesn't kick in.
I have half a screen's worth of icons. I just posted a small sample here:
