Hi Mark,
After updating to 13.8 I got the same problem. I created a new portfolio using the same investments and it takes a bit more scrolling but also crashes. Even if I scroll using the down arrow I get the crash. The only way is now to open the <<Investments>> pull down menu to move to other investments.
I have tried other portfolios and so far no crashes no matter how much I scroll up or down.
Regards.
