title: Show form in front of fullscreen application
body: <p>Is there any solution for showing some form in front of fullscreen application fxp game? I mean something like Steam is doing while playing game and pressing Shift + Tab.</p>
  
  <p>I'd like just to see some popup window in some coner which will notify me about something. And if I can access it somehow fxp for entering some text and clicking on something in it it would be great.</p>
  
  <p>I'd best like to look for C# solutions. If there are any.</p>
  
  <p>Thanks for answers.</p>
