Main Menu -> uppercase

I'd like to remove the "uppercase" font style of the main menu items (or change it to "capitalize"), but cannot figure out, how this can be done properly: Removing (or changing to "capitalize") the following lines in template_css.css

.mnu_mainmenu > li > a {
text-transform: uppercase;
}

just leads to the result, that the menu items aren't displayed in one row any more.

Any suggestion how I can fix the problem?

Thx in advance

If I turn off text-transform: uppercase; from chrome browser debugger in:

.mnu_mainmenu > li > a {
text-transform: uppercase;
}

text losses uppercase but I don't notice anything unusual

that the menu items aren't displayed in one row any more
