Hi there,

i noticed strange behavior in your avalondock version when i have textbox in floating LayoutAnchorable.
If textbox in floating layoutAnchorable has focus and you prey keyup/keydown this textbox loses focus (even if textbox has multiple rows and caret should move to next/previous line).

in this case, caret is in "second line" and key up/down will result into focus lost of textbox and dropDownAreaControl is focused instead (i checked that in Snoop).

If anchorable is docked or there are multiple anchorables joined together, up/down arrows works.

There you can find modified test app (but i only added textbox into properties window)

I noticed same behavior for combobox (also in example and richtextbox). And tried this in edi version 01_02 and didnt notice this behavior...
