I have installed Screenshot Captor and it automatically starts with windows. I want it to stay minimized, which is does. But the shortcut keys don't work. I have to make Screenshot Captor visible on the screen and navigate to Capture, grab selected region to be able to make a screenshot. How can I make the shortcuts working so that I can make a partial screenshot, just by typing Shift+PtrScr, even when the window of Screenshot Captor is not visible?
