I've noticed that Who's Online in admin (using v1.39c at the moment) is showing strange results.

Initially, it will show the correct link, such as /category1/product

If I keep hitting refresh, it then passes through a variety of template folders such as includes/templates/etc/etc/left_corner.png

This is obviously not what I wanted as it makes it very difficult to work out how customers are behaving on the site.

Spiders seem to report correctly with no problems. It's just real people who don't show the category/product correctly.

Anyone able to help me out?
