Bill,
1. Click Start, Run then type regedit. Hit enter.
2. Browse to HKEY_CURRENT_USER\Software\Yahoo\WidgetEngine\Widgets
3. You will find at this location all the widgets installed on your pc. Click on AquaStatus and hit the delete key. Do the same for any other names you might have used.
4. Close the regedit window.
This will remove all the settings for the widget. You can rename the widget back to Aquastatus or what ever you want to name it. Open it with the widget engine and you should be presented with the preferences window. Enter the FULL url to the status page. (i.e -
http://192.168.0.63/cgi-bin/status.cgi) The 192.XXX.XXX.XXX is ONLY VALID IN YOUR HOUSE. If you want to tuse the widget from a location outside you home, like from work or something. Then you have to get your domain address and router setup properly.
