Problem:
When you try to save the configuration of your List Rotator, you see this message. You click OK and things seem to work, but is everything really OK?
Resolution:
If you have selected Delay Effect in the Select Speed section of the tool pane, make sure you entered a value between 1-20.
If you forget to enter a value, the Value is Invalid message will appear when you click Apply or OK to save your configuration changes.
