Can the Finder be reset to all original Default Settings?
Note there is a specific motivation: I no longer can view external DVD/CD drives from Finder even though they both can play movies/music CD's: see DVD/CD Drive no longer shows in Finder . Resetting to Defaults would just be another thing to try.
Does setting the assign to Desktop:none; work for you.
You can do this from the Applications Dock menu.
How did you restore permissions? Manually, or did you use the "Repair" feature in Disk Utilities?
Restoring from a Time Machine backup from before things went bad should work.
One thing you might try before restoring is to delete the Finder preferences. ~/Library/Preferences/com.apple.finder.plist then relaunch the Finder (Hold Option while selecting the Finder icon in the dock). The preference file will be regenerated with the system defaults.
