So when my window opens, in the Loaded event, I set

```
MyTextBox.Focus();

```

and this works fine, Focus Visual is there, the caret blinks, I can type, no problem. Click on a node in a TreeView which I want to modify the textbox's text and re-focus the TextBox so the user can keep typing. I call:

```
    MyTextBox.Focus();

```

one more time. The focus visual does NOT appear on the textbox, and the cursor is NOT in the textbox. However, Keyboard.FocusedElement == MyTextBox is TRUE. Two oddities:

A) I have a button [\_Save] on the window. If I just press 'S' (no Alt- modifier), that button is pressed, like the window was taking my keystrokes!

B) if I press TAB on my keyboard, the first control on the window is selected, eventually, I'm able to select the control I want and it works perfectly.

There are no explicit focus scopes set anywhere.

Additionally, if I try traversals or InputManager.Current.ProcessInput(some tabs) or a few other ways to try to course the window into giving MyTextBox the focus *properly*, none of them work.

This is a regular WPF app without any special styling/templating, and I'm at my wit's end!
