This was great, I've been wondering about this for a while and figured it must have a cache to reset which ultimately means, "Will Google it later." I don't think I need to translate, "later" for the internet.
If I may add to this, my problem was that I have the cascading folders in my dock holding my dev tools, utilities, downloads and recent applications. Even after switching into and back out of icon view these icons didn't reset.
The fix is similar and simple and it's likely most will figure it out on their own.
Command + Option +Esc, select Finder, and click Relaunch.
I did this after I refreshed the aliases in the finder window. I'm unsure as to whether the order will matter or not.
Thanks again for your post.
