I downloaded Metro LX and SE 6.352 using the latest version of FireFox.
However when I tried to open the files it tried to use QuickTime Player. When I did the Command Apple-I it shows the files to be a MPEG video.
Now this has happened in the past and I always end up going to Safari.
My OS is 10.4.6 and run repair permissions and also DiskWarrior on a regular basis.
Not sure why I always have such problems downloading METRO updates.
