On RTL Site RC4 :hov element.style

iam working on RTL website using RC4 i finished about 95% of locale and theme i have this problem i didn't find how to fix it

On home page (theme : Septenary / )

Logo of the site and name of the site there is letter-spacing
over rides the css of showcase

original style.css
contains this

h2.septenary_showcase_title {
( letter-spacing: 10px;) this line is completely removed
margin-top: 10px;
font-weight:300;
font-size:36px;
text-align: center;
}


But on all browser this css override what i have modified on css

element.style {
letter-spacing: 10px;
font-weight: 300;
font-size: 36px;
}


and causes this error on letter of site name



Important notice , this happens on homepage only ! any other page (forum , Downloads, etc) no letter spacing !
