Task Manager 2; Folder Edit; Entering an invalid HTML Widget may never clear the "Fetching HTML Widget parameters, please wait..." message

When updating the HTML Widget field on the "HTML Widget" page of a Task Manager 2 folder, the message "Fetching HTML Widget parameters, please wait..." is displayed.

However, if you enter an invalid HTML Widget (e.g., select one from the list and add an "X" to the end), tabbing off this control never clears this message.
