Fixing a Slow Finder in Snow Leopard

I don't know if anyone else in the world will have this problem, but if your Finder is running slowly (and running at 90% CPU usage) after an upgrade to Snow Leopard, delete com.apple.finder.plist in your user Library folder, and it should return to normal.

Why mine did this, I'll never know, but using the old MacOS 9 adage of "delete the preferences" seemed to work here.

The whole computer seemed to be running slower with Snow Leopard, and because iStat doesn't work with 10.6 yet, I didn't immediately know what was going on. On further inspection of the Activity Monitor, Finder was using 90% of the CPU, so there was something going very wrong there. Deleting this file fixed it.
