Copy paste options are not working in dreamweaver

In my dream weaver copy paste options are not working. Its gives an erroraneous alert "While executing DWShortcuts_HTMLSource_Find_Replace command in menus.xml, the following JavaScript error(s) occured:".

The solution that i got from somewhere was to basically clear the configurations for dreamweaver.

C:\Documents and Settings\\Application Data\Macromedia\Dreamweaver MX 2004\Configuration

To acertain if this is the case, you can simply test it by moving the configuration folder to somewhere else. If it still doesnt work, simply put it back.

Now my dreamweaver works fine again without having to reinstall it.
