Many login accounts in the WWW are based on mail address as user name and password.
When I am using the Lap Dock (German keyboard layout) for logging in to any account via the Edge browser from the HP Elite x3 it is not possible to enter the @ character (AltGr +q).
The same issue happens in any field (url, comment etc. field) and the Edge browser is not usable anymore for a longer time until the cursor is coming back. So currently the Lap Dock in combination with editing fields in Edge is not usable at all whenever the @ character is needed.
However there is no problem to enter the @ character via Lap Dock into the Cortana search field or into any office document or when using the software keyboard on the HP Elite x3 directly.
In my opinion this problem is either caused by the Lap Dock itself or it is a bug in the Edge browser in combination with the Lap Dock.
In any case this issue is very annoying and needs to be fixed urgently.
May I ask if somebody could test this behaviour (in best case with a German Lap Dock keyboard) and to confirm? In the meanwhile I will try to find again a responsible developer.
