Open Flash Chart 2 not understanding "steps" in Internet Explorer

Question

Hi

I have a problem with Open Flash Chart 2.
It works like it should in FireFox, but in Internet Explorer my Y axis is all wrong.
No matter if I set the "steps" or not, it is not accepted in IE. Then it just takes my "max" and creates 5 steps with some weird numbers like 11.6, 23.2, 34.8, 46.4 and 58.
Why?

My JSON that I pass to OFC2 looks like this:

 var jsonStats = {
    "bg_colour" : "#FFFFFF",
"title": {
    "text": "<%=UCase(Left(MonthName(maaned),1)) & Mid(MonthName(Maaned),2) & " " & aar%>",
    "style": "{font-size: 20px; color:#000000; font-family: Verdana; text-align: center;}"
},

"elements": [
  {
    "type": "bar_glass",
    "alpha": 0.5,
    "colour": "#088A08",
    "text": "Besøgende",
    "font-size": 10,
    "values": arrVisitors,
            "tip": "Besøgende:<br>#val#"
  },
  {
    "type": "bar_glass",
    "alpha": 0.5,
    "colour": "#08088A",
    "text": "Sidevisninger",
    "font-size": 10,
    "values": arrPageviews,
            "tip": "Sidevisninger:<br>#val#"
  }
],

"x_axis": {
    "stroke": 1,
    "tick-height": 3,
    "colour": "#CCCCCC",
    "grid-colour": "#FFFFFF",
    "labels": {
        "labels": strDates
    },
        "offset": false,
        "steps": 1
},

"y_axis": {
    "steps": 10,
    "stroke": 1,
    "tick-length": 3,
    "colour": "#CCCCCC",
    "grid-colour": "#FFFFFF",
    "offset": 0,
    "max": intMaxValue
}
};

As mentioned, it works as it should in Firefox and Chrome, but not in IE and the only thing that IE does not understand is the "steps" bit.
