Thats a great tip. (But if you are all the way down at my level let me translate as I only learn't how to do this a few weeks ago.)
Do you remember in DOS when you hit "print screen" and everything on the screen would show up on the printer, but just the screen, not the whole page? And have you noticed that anymore when you hit "Print Screen" nothing happens? Guess What! When you hit "Print Screen" the image is captured on something called, 'clipboard' and is waiting for you to paste it somewhere else. You will have to open another program like "Word" or 'Notepad' and then click 'paste'. That will capture the image you are staring at on your laptop.
I will leave it to someone else to suggest the easiest way to move the image to the R3OWNERS.com forum.
