Windows 7 does not open minimized Windows, in what could be the reason?
Windows 7 X64 Enterprise.
With recurring frequency on the employee's computer happens следующtе: not open minimized Windows and applications (neither by mouse click nor via alt-tab), while new applications are opened in a maximized state (exactly as long as they don't collapse), I cannot view attachments in the Outlook mail client, they cannot be allocated (but these investments are allocated while holding the shift key).
Can't select text, the keyboard focus is not lost, and characters you can enter and delete with the keyboard. After some time the symptoms described earlier may be lost. For some time helps restart explorer.exe.
Will be glad to any assumptions about the causes of this behavior.
