dropdown SelectedIndexChanged not working on IE

[cesar.cortes]

Hi,

I have this dropdown that doesn't seem to work when i change its state
in IE. It works perfectly fine on FF.

When the state of the dropdown changes, the page posts back and
remembers the selection in FF but in IE it always defaults to the first
one.

Any idea on how to fix it and why this only happens in IE?

Here is the code:

..aspx page (the dropdown options get filled from a database):
<asp:dropdownlist id="dropArchive" runat="server"
AutoPostBack="true"></asp:dropdownlist>

code behind:

private void dropArchive_SelectedIndexChanged(object sender,
System.EventArgs e)
{
//some code here
}
