'1' is null or not an object

From CurvyCorners.net:

Bug: The script fails with the error:

'1' is null or not an object

when you specify multiple corners in a single css statement.

For example, the below breaks curvycorners (at least in IE8):

-webkit-border-radius: 8px 8px 0 0;

If I use seperate statements:

-webkit-border-top-left-radius: 8px;
-webkit-border-top-right-radius: 8px;

this error does not occur.

Also:

For those of you using curvycorners.js version 2.0.4 from the zip file and getting an IE8 error 'exec(...).1' is null or not an object ... you may want to check to see if your div has a microsoft.gradient filter on it. This version of the script breaks on line 1 char 13,871...

var n=filter?parseInt(/alpha\(opacity.(\d+)\)/.exec(filter)[1])

...is expecting you have applied an alpha (opacity) filter and breaks if you have applied a gradient! I didn't check this on the beta or SVN (I believe these versions fail silently).

HTH-

I got this error until I installed 2.1 version of curvycorners.
