I recently installed a program that would let me change some icons. I applied a new theme, and since then whenever I double click on a folder, rather than opening it, the default double click action has switched to "Search". I went back to the original XP icon scheme, but that did not fix the problem. I've rebooted several times with no luck either. Is there a registry key that controls what the default double click action is and how can I change it? Thanks. edit: here is a pic. As you can see, "Search" is the default action. How can I set it back to "Open"
