Version 3.5.11718.0: Problem with icon in system tray not showing when a new email comes in. It changes to an envelope only where before it was both the icon and the envelope. Is this a bug or new feature?
We used one tray icon for application and another for notifications and Windows somehow don’t support this well. So we unified both behaviors into one tray icon, which we believe solved the problem.
Improving the icon notification functionality might be done somewhere in future.
