The help says don't open the clipboard when you get a
WM_RENDERALLFORMATS, just SetClipboardData.

<help>
An application should not open the clipboard before calling
SetClipboardData in response to the WM_RENDERFORMAT or
WM_RENDERALLFORMATS message. 
</help>

So the proper response would simply be...

case WM_RENDERFORMAT:
case WM_RENDERALLFORMATS:
	  if (!ComponentState.Contains(csDestroying))
	  {
	    // add all formats using ::SetClipboardData()
	  }
	  return 0; // or Msg->Result = 0 for VCL handlers
