Crash when using <cmd> Z

[willyman]

I am currently editing a descendant chart with 305 people in 199 boxes.
My problem is that reunion crashes every time I use the "UNDO" function (Command Z).
I also notice that I often can't underline the name of a person with (Command U). It is not executed

I was not able to duplicate Reunion crashing when using the "UNDO" function (Command Z) for, either, editing text inside a box, or my deleting a box in a descendant chart. It worked fine for me. What type of editing did you do that you tried to undo?

The underlining of text inside a box SEEMS to work while the box is active and being edited, but when you click elsewhere to close the box the underlining does not take.
