My webpage with a free textbook has a simple html navigation.
Moving the cursor on the menu item makes
appear the menu item red, using onmouseover.
If I click that menu item, I get to the new page.
Everything works fine. But if I then bo back
with the back button (Mac Safari and IE - have not
checke on PC yet) I do get back to the previous
page, but with the choice of the next already/still highlighted.
(There are two red bars in this case.) Ugly.
All the programming is in html pages and in one css file;
nothing is hidden. (See http://www.motionmountain.net )
What is going wrong? How can one avoid this?
Any hint is appreciated.
