So what is this stuff?

DFX

In Panther, you can drag any application or document into the toolbar in Finder windows.  The "DFX" application is a small AppleScript that will display Default Folder X's menu (the same one that appears in the menu bar) whenever you click on the icon in the toolbar.  There's one inconsistency: because it's an application, you have to click and release the mouse before the menu appears.  It won't pop up if you just click and hold the mouse button, as normal menus do.

To install DFX, copy it to your Documents folder (or somewhere other than the original disk image on which the Default Folder X installer resides).  Then drag DFX from your Documents folder to the toolbar in any Finder window.  Once the existing toolbar items "slide aside" to make room for it, drop the icon there.  The first time you click on it, DFX may take a few seconds to configure itself, but it should be fast from then on.  To remove it from your toolbar, hold down the command key and drag it off the toolbar of any window in the Finder.

Don't show Default Folder X in DragThing

This script is useful if you're using DragThing and Default Folder X with its Dock menu turned on.

Because Default Folder X runs as a normal application when you tell it to appear in the Dock, it will also be shown in DragThing's process dock.  Unfortunately, Default Folder X's menus don't appear in DragThing's dock because DragThing doesn't support the Dock's popup menu API.  (Note that 'Dock' capitalized refers to the dock that Apple includes with OS X, while 'dock' in lowercase refers to the bars of icons that you can make in DragThing - confusing, no?)

ANYway, the script will change DragThing's settings so that Default Folder X doesn't appear in DragThing's docks (note the use of lowercase letters).  To use it, just double click on the script.
