Hi kwoolf !
This is css bug on IE, You can fix it by way :
open typo.css file in templates/ja_edenite/css folder. Find code section :
.legend-title {
PADDING-RIGHT: 3px; PADDING-LEFT: 3px; FONT-WEIGHT: bold; BACKGROUND: #ffffff; LEFT: 7px; FLOAT: left; PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-TOP: 0px; POSITION: absolute; TOP: -13px
}
.legend {
BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 10px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 10px; PADDING-BOTTOM: 0px; MARGIN: 20px 0px; BORDER-LEFT: #cccccc 1px solid; PADDING-TOP: 0px; BORDER-BOTTOM: #cccccc 1px solid; POSITION: relative
}
change it to :
.legend-title {
PADDING-RIGHT: 3px; PADDING-LEFT: 3px; FONT-WEIGHT: bold; BACKGROUND: #ffffff; LEFT: 7px; FLOAT: left; PADDING-BOTTOM: 0px; MARGIN: 0px; PADDING-TOP: 10px; POSITION: absolute; TOP: -13px
}
.legend {
BORDER-RIGHT: #cccccc 1px solid; PADDING-RIGHT: 10px; BORDER-TOP: #cccccc 1px solid; PADDING-LEFT: 10px; PADDING-BOTTOM: 0px; MARGIN: 20px 0px; BORDER-LEFT: #cccccc 1px solid; PADDING-TOP: 0px; BORDER-BOTTOM: #cccccc 1px solid;
}
good luck !
