Calling via icon and via print key should have same effect

[koppor]

When I call GrabNDrop via the icon, I can press Enter to select the area and Esc to cancel the action.

When I use printscreen, Enter has no effect. I have to press Enter,Esc to take the screenshot. At the next try, it is Enter,Esc, Enter,Esc. And the third time: 3x (Enter,Esc). Etc.
