There are several Terminal incantations that will make the default for  
Finder.app to display hidden files. Apparently you have your desktop  
machine set to one style and the other is still in the default mode.

Here's how to change it. From a Terminal window:
defaults write com.apple.Finder AppleShowAllFiles YES
And then restart the Finder with option-click on the Funder icon and  
choose relaunch. (or an alternative in the Terminal session would be  
to type:   killall Finder      )

The reverse effect is obtained by repeating with NO instead of YES.
