View using Windows Explorer. I get this option when in insert a CF card into my reader but it doesn't go there. I get MS editor. There must be a preference button somewhere.

Thanks in Advance

What is MS Editor? Is it a photo editor? If it is, there should be a setting within that program that tells it to launch when removable media is inserted. You should be able to turn it off there.
