Digsby update before it is possible not to update automatically. And now Digsby adding advertisements on the IM window which later earned income is used for development.
But there may be someone disturbed by it advertisements. Don’t worry….. it can be hidden.
Look for the option on the preferences as shown in the picture above. Uncheck the option that I mark red. Close the IM windows then open again.
You will not see the ads again.
