op=load op=view op=alter appearing on pages

A couple of days ago I began seeing a bulleted list of the following appear on my Drupal 6.2 pages.

# op=load
# op=view
# op=alter

There is one set for each node which is rendered on the page. If I then go to an individual node, I only see one set. Viewing the different admin tabs associated with the node, changes the bulleted list. If I click on the edit tab for that node for example, the list changes to the following.

* op=load
* op=prepare

I believe this may have occurred after enabling the devel module, but can't be certain on the timing, so I am not sure if this is posted to the right project or not, but figured it was a place to start.

I disabled and uninstalled the devel module, and neither of these changes made a difference. The bulleted list shows up for Anonymous or Authenticated users.

Can anyone provide some insight?

Thanks,

Darren
