I had been running Windows 7 as my operating system. I am not able to open all .jpg extension files in windows 7 photo viewer. Now the problem is that when I view pictures with the standard windows photo viewer, every time I open a picture from a folder, the pic opens up behind the folder I loaded it from annoying when I have to either go down to the task bar or aero flip to bring it to the front. Why i'm unable to open .jpg files in Windows 7 photo viewer? Any one has any idea about it? Kindly help me out to resolve the above issue. Thanks.
