I have done a clean install of the Windows 7 operating system. I am facing a weird situation in it that the Windows 7 Aero Peek is not working all the time. Everything works fine when the system is active. But, even if the system becomes idle for even 5 minutes, then this particular feature does not work. When I hold the mouse over a minimized window on the Taskbar, all I can get is the name of that window in text. I am not able to understand why this is happening. Please provide some help soon.
