>John,
>I would be happy to provide you with a simple settings class that uses the singleton design pattern. I have later versions that use other storage medium and also keep the actually settings seperated out. This is the simple version. My Settings stuff is alll in its own library called SettingsLib. To use this you just do the following:

Thanks!!! I fixed the bad tag here so I could copy it out.
