Dismayed to find out that MSN’s and Skype 4.2’s lack of a proper tray icon in Windows 7 is by design. According to this: “This icon pattern is no longer recommended for Windows 7. Use regular taskbar buttons instead if your program has desktop presence."
I think the taskbar is not the right place for icons that we use very rarely, but what do I know… For now the best approach if you don’t like this feature is to set the programs to run on Vista SP2 compatibility mode; in the long run I guess I’ll just have to get used to it. A pity, I love everything else about Windows 7.
Oh, and I still think there’s a bug with MSN showing two separate taskbar buttons.
