Windows 7: Pin to taskbar question

Hi everyone,

I have Windows 7 Pro on my notebook and I just setup a client with Windows 7 Home.

He has lots of Thunderbird email windows open and when you hover over the Thunderbird icon Pinned in the taskbar, you see each of the opened windows as a small representation of the window.
On my Windows 7 Pro I set it up the same, but each open window is represented by a horizontal line of text.
( much less real-estate and easier on the eye when you have lots of windows open! )

It this a difference between Pro and Home ?
I have looked everywhere for a setting that control this, but cannot find one !

If anyone has any ideas on this I'd really appreciate it...

regards, Dave

Right click on desktop and choose personalize. Are you using an aero theme?

Thanks that was it - I changed to a Non-Aero theme and got the display style I was looking for !

cheers Dave
