Mac OS X 10.2.8 or Earlier: Cannot Drag Items From Classic Applications to Trash

Some applications that allow you to drag items to the Trash when the computer is started up from Mac OS 9 may not allow the same action when the application is open in the Classic environment of Mac OS X.
Symptom

An item, such as a web browser bookmark or email attachment, is not deleted or removed when you drag it from a Classic application to the Trash icon in the Dock. Dragging items from the desktop or Finder windows to the Trash works correctly.


Solution

In Mac OS X 10.2 through 10.2.8, this issue will not occur if the Mac OS 9 System Folder used by Classic is installed on the same volume as Mac OS X.

In Mac OS X 10.0 and 10.1 (and Mac OS X 10.2 if Mac OS 9 is installed on a different volume), you will need to use an alternate method to delete the item. The method will depend on the application and the item you want to remove. For instance, for an email attachment you may need to locate the attached file in the Finder and drag it to the Trash from there. For buttons in the Mac OS 9 Launcher, you will need to open the Launcher Items folder inside the System Folder and drag the appropriate alias to the Trash.
