Page settings

ScriptCase Devel: 8.1.044
ScriptCase Build: 3
ScriptCase Prod: 8.1.044

In application-type “form” in layout / page settings do not work:

1 - Font Name (Font name used in the form tabs.)
2 - Font Size (Font size of the selected tab of the form)
3 - Selected Font Color (Background color of the selected tab)
4 - Non Selected Font Color (Font color of non selected tabs)
5 - Non Selected Background Color (Background color of non selected tabs)

The values are accepted and stored but the look and feel of application does not change!

It is a known problem? What can I do to solve it?
Thank you all.
