First off, I apoligize how I provide the example of this error. I tried to join the mailing list, but the confirmation email must not be working.

This expression generates an error:

alert($("#form input[@id$='Address1']").size());

The error:

Error: z has no properties
Source File: http://mlins.homeip.net/jquery/index_files/jquery.js Line: 710

However, this works in an older version of jquery(rev. 29) as seen here:

http://mlins.homeip.net/jquery/work.html

Click on "Geocode Address" to see the alert. Perfect.

Now with the latest version of jquery(rev. 249):

http://mlins.homeip.net/jquery/nowork.html

Same thing, click on "Geocode Address," this time the error from above.

Another intersting quirk, http://mlins.homeip.net/jquery/nowork.html works in IE.

I apoligize if this is my error, but jquery is very difficult for me to debug and I'm unable to join the mailing list.
