I am using jQuery and the cornerz plug in to get rounded corners on elements of the page without using images.

In IE7 and 8 it fails and I get this error:

"Object doesn't support this property or method"

on this lines:

  if($.browser.msie && settings.fixIE) {
      var ow = $$.outerWidth();
      var oh = $$.outerHeight();

Basically it complains about the outerWidth and outerHeight properties...

The cornerz demo page (here) works perfectly on IE7 and 8 without throwing any error and it has got several examples...I do not know why this is happening

Any suggestion will be appreciated

Thanks in advance
