R394 - Focus is lost when go back

[Dreamer]

- enter any folder
- go back using [..] item, go up button, or go up using backspace key
= it works good, previous folder is selected

but...
- go back using "history - back" toolbar button, alt+left, or mouse 'back' button
= previous folder is NOT selected, focus is lost

FC beta R394 and 2008.06c, Windows Vista SP1.
