Re-opening a message on pprune for editing doesn't display the attributes executed; it displays them as HTML. In the messages section, when one clicks on one of the checkboxes which select all the week's messages (for e.g. deletion) multiple selection fails to do anything.
With NoScript I find that you need to "allow" the site that you are on, i.e. if you click on the S at the bottom while in pprune, click on allow pprune.org, but leave the google stuff blocked, or if you want to see it for any reason click "temporaly allow". It can be a pain at times till you get used to it.
