In Version 3.4RC1 under Windows 7 both the "Left-To-Right" and "Right-To-Left" are visible on the "Formatting" toolbar even when they are set to be hidden (checkbox next to these buttons is in the "Customize Toolbar" panel is cleared). Selecting these items in (context menu)>Visible Buttons changed the state of the checkbox in the customize toolbar panel, but does not change the visibility of the buttons themselves, and the context menu item always appears checked. Also Version 3.3 has the reverse of the same problem - i.e. these two particular buttons are never displayed or their lines in (context menu)>Visible Buttons checked even when they are set to be visible. Should I raise this as a separate bug? I'm not sure as it looks likely to have the same cause as this one.
I saw the 'reverse problem' part with 3.4 RC1 on SLED 11 sp1 i586 that the 2 icons are never shown. Hi Cedric, I am not sure who's familiar with this area. Would you like to have a review if time? Thanks!
