Descendancy chart runs out of room and can't be scrolled/zoomed/moved
I realize that I can work around this by going down a couple of generations for my "top" person, but that's an annoying interruption of the process and likely to result in losing track of where I was.
I'm looking for record hints (blue boxes) in the descendancy of one of my spouse's ancestors. I've gotten so many generations in that the boxes are disappearing off the right-hand edge of the screen. There's a point where I can still just barely click one and get the chart to shove over a few millimeters.
But it doesn't help enough: if I expand another generation, all of the indicators disappear, and I have found no way of seeing whether those lower generations even have any hints. I can't scroll over, or zoom out, or pan.
Does anyone know of a way to get the descendancy chart to shove over a bit more? Why isn't there a horizontal scroll bar or a zoom setting or something to allow one to see the whole thing?
