ConfigurationSettings.AppSettings has a green line underneath showing a problem ... here is the appsSettings section of my web.config ...


<appSettings>
<add key="CrystalImageCleaner-AutoStart" value="true"/>
<add key="CrystalImageCleaner-Sleep"
value="60000"/>
<add key="CrystalImageCleaner-Age" value="120000"/>
<add key="ConnectionString" value="server=TESTDB;database=myDB;uid=test;password=passwd2;" />
</appSettings>
