Broken card stack in Squeak 6.0 64 bit

[jpenneygit]

It's entirely possible I do not have necessary upgrades, I am not sure how much detail you need.

Here's the reproduction steps:

Squeak 6.0 (64 bit)
create new morphic project
open Widgets tab
drag out Object Catalog
Select Presentation button
Drag out Stack onto working area
Click Basic button in Object Catalog
Drag ScrollingText object into stack
click "+" button on stack
-- Error appears, "MessageNotUnderstood: Player120>>commitCardPlayerDataFrom:

---

Here's the stack trace:
