Wow! So much to learn. I haven't heard of a focus frame. What's that? Is it a tool that you can use?
Hmm I did the update and Im not getting that...maybe its a setting in your EASE OF USE options?
If I'm on the start menu, and press a direction key, it highlights (focus) a tile; and subsequently, each adjacent tile moving up, down, left, right. If I use the touch screen and swipe, the focus disappears. Does the focus disappear when you swipe it? If it does, I wonder if the keyboard is sending an "up" signal, or the tablet thinks it is?
Append: Have you rebooted, and/or re-attached your keyboard as a remediation attempt?
You say all users have this issue. Do you mean this literally? Mine does not have a focused tile unless I press a key.
Hi since the update yesterday I got a focus frame around the top left tile.
nice for keyboard use but not so nice on the SP3.
