UI glitch: can't use arrows after changing note value

Does this happen to other pople too? Is this to be considered a bug?

1) Open a score
2) Select a note head
3) Change its value (shorter or longer does not matter): the note is still selected (blue)
4) Try to move to previous or next note (chord) with the [Left] or [Right] arrow:

Result: selection does not move; a mouse click (even on that same note head) is necessary to restore the functionality of the arrow keys.

The same happen with some other modifications to a note, but I do not remember which ones right now -- I'll quote when I meet them; this case is the most common, though (at least for me).

Thanks,

M.
