   Translucency redraw issues

   Hi all.   
      
   I have just added translucency to one of my applications using the   
   layered windows API, but I have come across a redraw problem.   
      
   Unfortunately, I cant reproduce this in a standalone app but I'll try   
   and explain what's happening.   
      
   When a form is obscured when it is resized or made "visible" (I show   
   some other forms on restore), it seems to remember that visibility   
   state. When it is then unobscured, it fails to redraw most of the window   
   leaving it black (but translucent black :)   
      
   Covering and uncovering this window makes no difference, and I can only   
   seem to force a redraw by manually calling refresh on EVERY object on   
   the form. Any control that is explicitly redrawn (gets focus, mouseover)   
   also appears correctly.   
      
   This happens regardless of the actual alpha level set.   
      
   Has anyone seen this before or even better, have a solution?   
      
   Thanks
