I was on Ancestry.com and was guilding a ancestor chart and had about 4-5 generations. The complete chart would not show on the screen and I was trying to add to chart on extreme right and had to move everything over to left to have room to add to chart. I held the Ctrl button down and moved my mouse and the whole chart moved off the screen to the left. How do I get the chart back on screen, and when I do get it back, how do I maneuver screen so I can add to chart on the right?
