I've decided to run Fences as an alternative to OD+. However, even though I have unchecked "Load at Startup", it continues to do so. The only solution was an uninstall. After reinstalling (I don't want to permanently remove OD+) however, the problem returned.
Here are my setting and the msconfig screens:


I also used regedit to make sure it wasn't listed in HKEY_CURRENT_USER\software\microsoft\windows\currentversion\run or HKEY_LOCAL_MACHINE\software\microsoft\windows\currentversion\run. Is there another location I can look?
