Panel layout

I saved my panel layout in Flash MX 2004 Prof for PC, but now I can't delete the saved panel sets. How do I do this. In Photoshop it is easy, there is a delete button for the panel set you created, I expected the same thing in Flash. See attached files of panel layout options in flash vs. photoshop

got this from the macromedia site.

Deleting custom panel set layouts: Open the folder for the Panel Sets documents in the location for your operating system (listed below) and delete the text file for the custom panel set.

For Windows operating systems:

Windows 2000 or XP: C:\Documents and Settings\user\Application Data\Macromedia\Flash MX\Configuration\Panel Sets

Windows 98 or ME: C:\Windows\Application Data\Macromedia\Flash MX\Configuration\Panel Sets

Windows NT: Windows directory\profiles\user\Application Data\Macromedia\Flash MX\Configuration\Panel Sets
