I am using Windows 7 on my computer and I am having strange problem and I have decided to discuss with you all. Well I have found that whenever I double click on any folder it does not open. However I can see at taskbar that particular folder is open and I can also see the content of the file by review icon. But when I click on it folder does not maximize. Now I am confused why this is happening. I think there is bug in to the operating system. Any help will be highly appreciated. Thanks in advance.
