Assign the Finder to all Spaces
Spaces is a great feature of Leopard, as I’ve previously discussed. Often I’ll find myself needing to access a Finder window in another space (e.g. top open a file in a certain app, to attach a file to a mail message, etc.). Though you can easily switch spaces while dragging a file, it’s more convenient to have access to your Finder windows in every space. Here’s a tip frommacosxhints.com on how to do just that. Basically, you just go into the Spaces panel in System Preferences and add the Finder as an application by looking in /System/Library/Core Services/Finder.app. Then choose “Every Space” for it’s space.
