I have a few folders that each contain several hundred .jpeg files, and icon preview enabled for each of them. I find that if i open one of those folders briefly and then close it again the Finder's CPU usage spikes dramatically - essentially using every available cycle.

While it makes sense that when i open one of the folders the Finder would be busy loading all of the icon previews, this should really stop once the folder is closed imho. The strangest thing about it though, is that sometimes i have let the Finder do whatever it is doing for about 10 or 15 minutes and then gone back to the folder in question. I had expected to find many/most of the icon previews to be loaded by then, but they weren't.

So it seems to me that the Finder gets busy not doing something that it thinks it is doing...

I don't expect 10.3.7 to fix this either, since it has been around for a while. Maybe 10.4 will.
