Mail app will not open on 10041.

Hello Adam,

This is the suggested solution below if you haven't already tried it.

In this Windows 10 build 10041, the Mail, Calendar, and People apps may be broken due to a licensing issue with the Store Beta. To get these apps working again, you need to follow these steps:

• Open powershell as administrator
• Run the command Get-appxprovisionedpackage –online | where-object {$_.packagename –like “*windowscommunicationsapps*”} | remove-appxprovisionedpackage –online
• Re-install Mail, People and Calendar from the Store (green tile)

 

UWP - Focus issues when opening a flyout from an AppBarButton

I'm facing the following issue in a UWP app targeting the "anniversary update" SDK build 14393.

When opening a Flyout from an AppBarButton, the controls inside the flyout lose their ability to be focused when clicked/tapped (tab still works, though). If the same Flyout is assigned to a Button then focus work as expected.

Here's some code to reproduce the issue (create a blank UWP project and copy & paste it into the main page grid):

<!-- in the dark theme focus is more visible -->

<StackPanelOrientation="Horizontal"VerticalAlignment="Center">

<ButtonContent="Button">

<Button.Flyout>

<Flyout>

<StackPanelOrientation="Horizontal">

<TextBox/>

<ButtonContent="OK"/>

</StackPanel>

</Flyout>

</Button.Flyout>

</Button>

<AppBarButtonContent="AppBarButton">

<Button.Flyout>

<Flyout>

<StackPanelOrientation="Horizontal">

<TextBox/>

<ButtonContent="OK"/>

</StackPanel>

</Flyout>

</Button.Flyout>

</AppBarButton>

</StackPanel>

When I run the above code and open the Flyout by clicking "Button", clicking alternatively the TextBox and OK Button inside the Flyout cause the focus to move between the controls as expected. However, when I open the Flyout by clicking "AppBarButton" the
focus doesn't move when the controls inside the Flyout are clicked.

[Edit, More details] When the Flyout opens from the AppBarButton the focus isn't transferred to the Flyout but stays on the page. You can see this by pressing Tab.

Is this a bug or am I missing something?
