Help plz about print screen pics

Hi, Im trying to do a print screen of my weapon so i can post it on the forum to sell. But for some reason my final pic is not showing the stats of my weapon. this is wat I did.

Moved mouse of weapon
waited for the bubble of the stats window to appear
press print screen

But when I went to my directory where the pics been saved, its just my toon standing there with no user interface.
Can anyone explain how to go around this? I think its someething with my option. not quite sure..

Did you hold shift down when taking the shot? If you did then that removes all the UI from the shot.
