SYMPTOMS
When you use Remote Desktop Connection to access an application that was built by using Microsoft Windows Presentation Foundation, the following items have solid black edges instead of transparent shadows:
 * Menus
 * Lists
 * Tooltips



CAUSE
This problem occurs because Remote Desktop Connection is configured to use the &quot;256 Colors&quot; mode. In this mode, the transparent sections of the window are displayed as solid black.



WORKAROUND
To work around this problem, disable shadows. To do this, follow these steps:
 * 1) Click Start, click Run, type sysdm.cpl, and then click OK.
 * 2) Click the Advanced tab, and then click Settings under Performance.
 * 3) Click the Visual Effects tab, click to clear the Show shadows under menus check box, and then click OK.



RESOLUTION
To resolve this problem, configure Remote Desktop Connection to use the &quot;High Color (15 bit)&quot; mode. To do this, follow these steps:
 * 1) Start Remote Desktop Connection.
 * 2) Under Logon settings, type the location of the computer to which you want to connect in the Computer box.
 * 3) Click the Display tab.
 * 4) Under Colors, click High Color (15 bit), and then click Connect.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.
