I'm not sure whether this bug is to do with -

a) removing a row from a table, for use with later .clone() operations

b) dynamically appending rows to a table

c) dynamically assigning a .dblclick() function to a row

d) some interaction between blockUI and a and a -> c above.

I've made the smallest example of this for easy-reproduction. Just satisfy the following:

<script type="text/javascript" src="jquery-1.2.6.pack.js"></script>

<script type="text/javascript" src="jquery.blockUI.min.js"></script>

If the rows are hard coded and the dblclick(..) handler are set globally, it works fine.

On the page that displays, fist double-click 'one' (then cancel that popup div) then do the same to 'two'. 'one' and 'two' are rows in a table.
