When I try to view small mpeg files on a web site Internet Explorer freezes.Microsoft help pages do not seem to list this as a problem. An example site I am having problems with is click here This is the officiah Hubble Space site where you can view small mpeg files on line before downloading the larger files. I can donwload the large files and run them in Media Player without any problem but this means I am dowloading lots of files that I do not need. I have reset all I.E. sttings to their default but the problem persists.Is it perhaps something to do with Norton Antivirus?
