I have a computer running Windows 7 Pro.  I am unable to download files off of the internet.  When I click on a file to download, it brings up the box and I can select where I want the file to be downloaded to.  Then I get the green status bar to show the download progress. When it gets to where it should be 100% complete, the download box closes and the file is not downloaded.  Any ideas on how to fix this would be appreciated.
