css:--- /* hide the dotted lines around an element when it receives focus */
* { _noFocusLine: expression(this.hideFocus=true); } /* ie7 */
::-moz-focus-inner {border:0;} /* firefox */
:focus {outline:none;} /* ie8, chrome, etc */

Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack
" Unable to evaluate expression because the code is optimized or a native frame is on top of the call stack" - This is one of the common error we see in forum where people request solution for it.
Below is a small explanation and resolution to resolve this issue,
This error normally occurs when we use Response.Redirect or Server.Transfer or Response.End in your code before completing the actual process the page was doing.
In this case what you have to do is
In place of Response.End you have to use HttpContext.Current.ApplicationInstance.CompleteRequest
and in place of Response.Redirect, use the Response.Redirect ("Paganame.aspx", false);
and in place of Server.Transfer, use the Server.Execute method
There is also a KB article related to this issue,

Removing Dotted Border on Clicked Links using JQuery
var links = document.getElementById('nav').getElementsByTagName('a');
for ( var i = 0; i < links.length; i++ ) {
links[i].onmousedown = function () {
this.blur();
return false;
}
links[i].onclick = function() {
this.blur();
}if ( /msie/i.test(navigator.userAgent) && !/opera/i.test(navigator.userAgent) )
{
links[i].onfocus = function() { this.blur(); }}
}
$('a').live('mousedown', function(e) {
e.target.blur();
e.target.hideFocus = true;
e.target.style.outline = 'none'
}).live('mouseout', function(e) {
e.target.blur();
e.target.hideFocus = false;
e.target.style.outline = null;
});
