Hi Rednbing,
In Window Blinds, click on Colours at the bottom of the page and then on change system colors. You can change any that you like including menu text. OR you could go to the Control Panel, click on Personalization, Window Color and then on Advanced Appearance Settings to see if it is a system color that is causing the problem. Just scroll down and select Menu and you can see the background and the text color. Hope this helps a bit.
