http://forums.dropbox.com/topic.php?id=28265  v1.0.0:  
* Stop the Dropbox location changer widget from jumping all over the place in the tour. 
* Fixed case where the Dropbox preferences window wouldn't always become active when clicked from the menu bar on Mac OS X versions before Snow Leopard. 
* New "Easy Relink" dialog in the tour. Now when you link with the same account as a previous installation you will be greeted with a fast path to configuring Dropbox. This retains your Dropbox location setting as well as your selective sync settings. 
* Selective sync is optimized to finish *a lot* quicker when changing settings during initial sync. 
* The Dropbox tour is now more careful about merging your dropbox with a previous installation. 
* Better handling of folders which names like ".dropbox" or "Desktop.ini", having folders with these names could cause Dropbox to spin in some syncing situations. 
* Dropbox will now be more aggressive about making sure to not add duplicate entries to the Finder sidebar. 
* Fix random bug that would prevent preferences to show up when you opened it for the first time at a rare point on Windows. 
* Don't enable Growl notifications for all compatible apps if you didn't have Growl installed before installing Dropbox. 
* "Move Dropbox" was broken in some cases on Windows, now should be a lot better. 
* Fix the context menu not showing up sometimes on Mac OS X versions before Snow Leopard.  
Have fun guys! Thanks so much for testing!
