Tracking ID 693-54: CFSA Can Incorrectly Deny Drag-and-Drop onto Dropbox Shortcut

Occasionally and only under specific conditions, the Client File System Agent (CFSA) incorrectly blocks a DropBox drag-and-drop operation. This can happen when a user drops a file onto the DropBox shortcut on their desktop.

Normally, DropBox starts automatically and runs as a background instance when a user logs on. If the user drags a file onto the DropBox shortcut, a new instance of DropBox starts. The new instance runs long enough to sync the file with the DropBox web server and then stops.

However, if the background instance of DropBox is not running, the new DropBox instance continues running after the file has been synced. The CFSA is unable to interact correctly with the still-running DropBox instance. As a result, the CFSA allows the initial drag-and-drop operation but blocks any subsequent operations. Specifically, if the user attempts to drag a second file onto the DropBox shortcut, the CFSA denies access to the DropBox sync folder and displays the Access Denied message (as defined in user policy).

The workaround to this problem is to log off. When the user logs off and then logs back on, the correct background instance of DropBox starts and the CFSA correctly handles drag-and-drop operations to the DropBox shortcut.

Note: This CFSA problem can only affect drag-and-drop operations to the DropBox shortcut on the desktop. This problem does not affect drag-and-drop operations to the DropBox folder in Windows Explorer or uploads to the DropBox web site.
