Hyperlinks not changing colors after visiting them

Using LO 4.4 Impress on Windows 7 (Eng), I am trying to hyperlink to various slides in presentation. The hyperlinks are not changing colors after I visit them. I have already used the method below to select colors:

menu Tools → Options → LibreOffice → Appearance

But it is changing the visited colors or the unvisited colors. What else can I try?
