Could you please show your code? It is very difficult to pinpoint what portion of your code that may not be compatible with IE from what you explain.

Hi,
I have developed a small application which makes use of ajax combo box drop down list. Problem is it is taking time while getting loaded on internet explorer. But i have seen it to work normally on other browsers. Can any one suggest me how can even make it to work normally on IE.

I think this is an ASP question, despite its AJAX angle.

I can find nothing remotely familiar or comprehensible in the code and feel that denizens of the ASP forum might fair better with it.

Have you made certain that your page is not rendering in quirks mode? Quirks mode in IE can cause slow javascript (though it is usually seen with jQuery).
