Hello Pascal,

At present there are two ways:

1. You can always hit "Ctrl-PrntScreen" to copy 
   the selected "window" to the Windows clipboard. 
   Then you can apply the "Paste" operation from 
   any Windows application as usually.

   For example you can paste to the Microsoft 
   Photo Editor and then save it. 

2. Install ROOT from http://root.bnl.gov 
   Use: http://root.bnl.gov/QtRoot/QtRoot.html#gifbatch 

                 Hope this helps, Valeri
