I'm experimenting a issue in which with the configuration in subject the webviewer ignores the pressing of the @ key and of the # key.
If I build the runtime without kiosk mode it all work. The same happens if I open the solution with Pro or Advanced.
The problem is independent rom hardware; i tied also emulating with parallels, on 2 PC, also with a touch screen using both the win10 keyboard and a third-party keyboard simulating App
On runtime mac non problems at all.
