TOPIC: I can't delete old locations from location manager

I need help, I can't delete old locations from location manager, and ideas? I am running 2.7.8. I will select the location and delete it. I get a message that says DT_LOCATION_DELETE_WARNING when the page refreshes and the location is still active. I have roughly 40 old locations I need to delete so that my search list on my class listing page is current. Thank you

Is anyone else having this issue? I still can't delete the locations not to mention that when i'm using my mac I can't save, apply or delete any changes to the module (I have a 2 month old macbook pro). I have to use a pc to be able to do any of that which is kind of annoying. Any help would be greatly appreciated. Thanks
