I found something else interesting. When you double-click the 'cydoor_uninstall.exe' and it gives you the normal "Error Loading C:\WINDOWS\System32\cd_clint.dll" message it always gives you when cydoor is not installed. However, while watching my registry while performing this operation, I noticed that cydoor_uninstall.exe also creates a registry key at HKLM\SOFTWARE\Cydoor. It has no values, but it's there just the same. Why is this so? If cydoor_uninstall.exe is supposed to clean up cydoor when LimeWire uninstalls, why does it create a key that is going to be left behind?
