Had Windows 7 Installed 2 months and when I first got it, if i clicked on Thumbnails on Taskbar at the bottom, any opened Programs would show on Desktop, but what i get now is `only the description of program opened, on a narrow strip instead of larger type icon, showing more detail, as example Firefox
How can I restore it, nothing mentioned in Windows 7 Help under Aero Peek, what am I overlooking.
