IM Tab Orientation Selector should say "restart required"

Description

When changing the tab orientation on the [Preferences > Chat > IM & Groups] panel, the selection between Horizontal, and Vertical Tab Orientation does not take effect until restarting the viewer.

Some indication that a restart is required, would be helpful.
