Tablet keyboard disappearing when tapping on an entry field

There is a known issue where, when the tablet user tries to tap on a field to enter data e.g. a product quantity, the keyboard will popup but then immediately disappear.

This is due to a change that Microsoft made with how the on screen keyboard interacts with the the current app. By default the keyboard is now interacting with the app rather than sitting on top of it.

To get the keyboard to pop up on top of the app,

Pop up the keyboard using the keyboard icon on the taskbar.

Tap the keyboard settings icon

Select the on top option.

The keyboard should now float on top of the app rather than try and interact with it.

There is also a registry setting that might need to be set to allow this to be changed:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\TabletTip\1.7
REG_DWORD DisableNewKeyboardExperience = 1
