Line 455 in the 2.1.1 source:
var trans = filter ? parseInt(/alpha\(opacity.(\d+)\)/.exec(filter)[1]) : 100; 
// IE8 bug fix

if you test the regular expression against filter first, you won't get an error 
if exec() returns null. So:

var regExpFilter = /alpha\(opacity.(\d+)\)/;
var trans = regExpFilter.test(filter)[1] ? 
parseInt(regExpFilter.exec(filter)[1]) : 100; // IE8 bug fix

dr.za...
Where does this code go? I think this is the fix, but I have no idea where to 
put the code. 

Thanks for the help!

@dbran...

I had the same problem, so I edited the existing (full code) and packed it 
again. Give it a try...

@Karel.

Today, I got a bug for my registration form. i am using asp.net validator but 
in middle i have also done some custom validations by hiding some table row and 
span in it.

When i revoke that table row and span, rounded effects not applied to the span 
on which i am applying the rounded corners.

My validation error comes in rectangle without rounded effect.

I have checked below with the site instructions 
http://www.curvycorners.net/instructions/

I found Using Asp.Net option and redraw function to revoke, but @Karel i am 
using you 
jquery.curvycorners.js script in which curvyCorners function is not defined so 
i get that error in ie of undefined. 

Also i have try to use there curvycorner.js from there site but i get error 
Object doesn't support this property or method.

And it gives nothing to redraw alert from there curvycorner.js file and also no 
rounded effects applied to validation errors.

This is the code i am using with your script it works fine for default 
validation errors, but not for the case i have mentioned above.

<!--[if lte IE 8]>
<script src="/Scripts/CurvyCorners/jquery.curvycorners.js" 
type="text/javascript"></script>
<script type="text/javascript">

    $(window).load(function () {
      //For Rounded Corners on top Navigation

        $(function(){   
          settings = {
            tl: { radius: 6 },
            tr: { radius: 6 },
            bl: { radius: 6 },
            br: { radius: 6 },
            antiAlias: true,
            autoPad: false,
            validTags: ["div"]
          }

        $('.errorBg').corner(settings);

          });
    });

   </script>
<![endif]--> 
One doubt would you please clear?
If i use the script file from curvycorners website so do i have to include 
jquery file for same?
But i am seeing no reference to any jquery file in there website?

Can you please help me out how i can redraw the elements with your script.
Urgent reply would be more helpful.

Thanks.
