New description:

 When I delete category, software initiates ajax request to the server,
 then delete item from the table by ajax response, correct? If so, after it
 I get JavaScript error: Object doesn't support this property or method.

 I use IE7 and thought that this bug in JavaScript with new IE release,
 then I checked it to Firefox and got this JavaScript error after deleting
 category (copied from JavaScript console):

 $(id) has no properties[[br]]
 http://my.domain.com/wp-includes/js/list-manipulation-js.php?ver=4187

 Also, as I can see sometimes when I receive this error I also get this
 alert box (mostly Firefox):

 Are you sure you want to navigate away from this page?[[br]]
 Slow down, I'm still sending your data![[br]]
 Press OK to continue, or Cancel to stay on the current page.

 This bug presents in IE all time, but in firefox only for first deleted
 item. Then I do not see any errors, deleting goes well.
