Animation externder not resetting after hittilg close

I am using the standard AJAX animation extender. After hitting the close button, If I need click the anumation button again, the screen scrolls. How to make it stay on the original spot:

.flyOutDiv
{
     display: none;
     position: absolute;
     width: 400px;
     z-index: 3;
     opacity: 0;
     filter:(progid:DXImageTransform.Microsoft.Alpha(opacity=0));
     font-size: 14px;
     border: solid 1px #800000;
     background-color: #FFFFFF;
     padding: 5px;
}
.flyOutDivCloseX
{
 background-color: #666666;
 color: #FFFFFF;
 text-align: center;
 font-weight: bold;
 text-decoration: none;
 border: outset thin #FFFFFF;
 padding: 5px;
}<asp:LinkButton ID="Qinst" runat="server" Text="Instructions" OnClientClick="return false;" /><table><tr align="left"><td><div id="moveMe" class="flyOutDiv"><div style="float:right;" ><asp:Button ID="btnClose" Text="X" runat="server" OnClientClick="return false;" CssClass="flyOutDivCloseX" /></div><br />
