Hi Gustaf,
thanks again for the reply. I've commented out the filters on the dev environment and everybody is happy for the moment. We've decided it's probably a good feature to have in the live environment, so I'm not going to change anything there.
Yes, before the upgrade we didn't use the request monitor.
The buttons go to a page that then does a ad_returnredirect back to the current page. So you end up with a bunch of clicks all using ad_returnredirect to go to the same page.
thanks for all your wonderful help
Brian
