Summary:  NullPointer Exception in BeginInvoke(..) of 
System.Windows.Forms/Control.cs

Original Submission:  There is a NullPointer Exception at line 
"toolkitWindow.SendBeginInvoke(i_gch);"
in method BeginInvoke(Delegate method, Object[] args) of 
System.Windows.Forms/Control.cs 
The exception occurs if the control's handle does not exist when calling 
BeginInvoke(..).

I did a quick hack to solve the problem:
create the handle if necessary.

if( null == toolkitWindow )
   CreateHandle();

lock(this)      
   toolkitWindow.SendBeginInvoke(i_gch);
