TTMSFNCListBox component and down arrow key

BUG: drop a TTMSFNCListBox component on a form. Put it breakpoints on these events:

  1. ItemSelected
  2. ItemKeyDown
  3. ItemKeyPress
  4. ItemKeyUp

Unexpected behavior:

  1. Events 2, 3, and 4 never fire with any keypress.
  2. ItemSelected fires for UpArrow key but not DownArrow key (either numeric or regular keyboard). End, Home, PageUp, PageDown work as expected.

For what it's worth, I see this down arrow not working behavior on 1.0.4.0 but not 1.0.3.1.

We could reproduce this. It is an unfortunate regression in TMS FNC UI Pack v4.
We're working to have a fix asap.
