Schriftgröße im Menü falsch wiedergegeben durch IE

Hallo zusammen!
Hab ein Problem bei der Ausgabe meiner Site mit dem IE (Mozilla läuft problemlos).
Wenn ich in meinem linken Menü auf einen Menüpunkt klicke oder drüberfahre, ändert sich die Schriftgröße (aber nur beim IE, zumindest in Ver.6.x)). Wie kann ich das korrigieren? Oder gibts da eine gute Doku zu?

Mein CSS sieht so aus

/* Left_nav Menu Navigation */

.left_nav	{ 
	font-family: Verdana, Arial, sans-serif;
	font-size: 15px;
	color: #666666;
	line-height: 25px;
	background-color: #EEEFEA;
	width: 160px;
	text-decoration:none; 
	background-repeat: no-repeat;
	background-position: top left;
	}

table.left_nav		{ 
	background-color: #EEEFEA; 
	text-decoration:none; 
	}

.leftnav-level1-NO		{ 
	margin-left: 8px;
	}

.leftnav-before-img		{ 
	margin-left: 0px;
	vertical-align: bottom;
	}

a.leftnav-level1-NO		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 15px;
	color: #666666;
	line-height: 25px; 
	text-decoration:none; 
	}

a.leftnav-level1-NO:hover		{ 
	color: #3366CC;
	text-decoration:none; 
	}

.leftnav-level1-ACT		{ 
	margin-left: 8px;
	}

a.leftnav-level1-ACT		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 15px;
	color: #666666;
	line-height: 25px; 
	}

a.leftnav-level1-ACT:hover	{ 
	color: #3366CC;
	}

.leftnav-level2-NO		{ 
	margin-left: 15px;
	}

a.leftnav-level2-NO		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 11px;
	color: #666666;
	line-height: 16px; 
	}

a.leftnav-level2-NO:hover		{ 
	color: #3366cc;
	}

.leftnav-level2-ACT		{ 
	margin-left: 15px;
	}

a.leftnav-level2-ACT		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 11px;
	color: #666666;
	line-height: 16px; 
	}

a.leftnav-level2-ACT:hover		{ 
	color: #3366cc;
	}

TD.leftnav-level1-BOX-sm		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 5px;
	color: #666666;
	line-height: 5px; 
}

TD.leftnav-level1-BOX		{ 
	font-family: Verdana, Arial, sans-serif; 
	font-size: 15px;
	color: #666666;
	line-height: 25px; 
	border-bottom-width: 1px; 
	border-bottom-style: solid; 
	border-bottom-color: #FFFFFF; 
	}

# ------------------------------
# Left Menu Navigation

temp.leftnav = HMENU
temp.leftnav.1 = TMENU

temp.leftnav.1 {
  # Normal state properties

  }
 }


# Third level menu-object, textual
temp.leftnav.3 = TMENU
temp.leftnav.3 {

    after = <br />
    ATagBeforeWrap = 1
  }

  # Enable active state and set properties:

  ACT {

    ATagParams = class="leftnav-level2-ACT"
    allWrap = <div class="leftnav-level2-ACT">    | </div>
    beforeImg =  EXT:tmpl_urbannomad/template/images/arrow_grey.gif

    beforeImgTagParams = hspace=5
    RO = 1
    after = <br />
    ATagBeforeWrap = 1
  }
 }

Das ganze ist mit dem template urban_nomad gemacht. Was ist zu tuN?

Nicht wirklich ein T3-Problem
Definiere in deiner CSS doch einfach eine feste "font-size" für "hover" und "active" deiner Menülinks.

Danke Norman!
Dann werde ich mich mal bisschen mit CSS beschäftigen!
