Hi jmilton,
At the moment, the best option would be to register the Icon.StopGreen during the intial Page_Load. Then during the AjaxEvent/AjaxMethod, setting Icon = Icon.StoreGreen will work.
The following sample demonstrates.
Example
<%@ Page Language="C#" %>
<%@ Register Assembly="Coolite.Ext.Web" Namespace="Coolite.Ext.Web" TagPrefix="ext" %>
<script runat="server">
protected void Page_Load(object sender, EventArgs e)
{
if (!Ext.IsAjaxRequest)
{
this.ScriptManager1.RegisterIcon(Icon.StopGreen);
}
}
protected void Button1_Click(object sender, AjaxEventArgs e)
{
this.Window1.Icon = Icon.StopGreen;
}
protected void Button2_Click(object sender, AjaxEventArgs e)
{
this.Window1.Icon = Icon.StopRed;
}
</script>

Icon="StopRed">
<Buttons>
<ext:Button ID="Button1" runat="server" Text="Set Green">
<AjaxEvents>
<Click OnEvent="Button1_Click" />
</AjaxEvents>
</ext:Button>
<ext:Button ID="Button2" runat="server" Text="Set Red">
<AjaxEvents>
<Click OnEvent="Button2_Click" />
</AjaxEvents>
</ext:Button>
</Buttons>
</ext:Window>
</form>
</body>
</html>
Hope this helps.
