Hello,
If you're using Windows you could Alt+PrintScreen to copy the current window to the clipboard. There's a free graphics program called IrfanView which you could paste into and crop how you want it. Then copy/paste into Powerpoint, or save as a JPEG and import it that way.
Does any one know how to cut and paste a board set up to power point. I wanted to make slides on different openings and some variations in a power point presentation to help remember the lines. Thanks
