#4 Stack display not refreshed upon window sizing

[FabriceB]

Bon ben tout est dit dans le titre :)

When resizing the calc window, the newly displayed
parts of the stack panel are not updated.
If a vertical scrollbar is displayed, when resizing in a
manner the stack is tall enough to display all items, the
scrollbar is not hidden.
Minimizing, the restoring the calc window corrects the
display.
