Summary:  Control.ContainsFocus causes an stack overflow

Original Submission:  If U derive a class from control and overwrite the get 
property Focused and then call ContainsFocus within this U'll get an 
StackOverflow.
Try this:
public class MyControl : public Control
{
 public override bool Focused
 {
  get
  {
   return this.ContainsFocus;
  }
 }
}

if U call MyControl.Focused -> Stack Overflow.

I did a quickhack in Control.cs:

public bool ContainsFocus
{
get
{
 // Heiko Weiss, do not call Focused, maybe some derived classes overwrite 
Focused 
 if(toolkitWindow != null && toolkitWindow.Focused) return true;

 /* Do not do the following lines
 if (Focused)
 {
  return true;
 }
 */
 for (int i = 0; i < numChildren; i++)
 {
  if (children[i].ContainsFocus)
  {
   return true;
  }
 }
 return false;
 }
}
