[Orgmode] agenda actions unexpectedly open files

[Michael Gilbert]

Hi --

This is so odd.

Most of the time, but not always, when I mark an item as DONE in the  
agenda, it pops open the file containing the item. I'm just now  
noticing that it's doing the same thing when I clock in. This  
obviously really messes with my workflow.

This started someplace along my upgrade process, but I can't put my  
finger on when. I'm running Aquamacs Distribution 2.0preview3 (GNU  
Emacs 23.0.94.1) with org-mode 6.32, but this has been happening for a  
few weeks now.

Any advice?
