It is not here either but then again I'm on a Mac.
And is there no option to change this behavior in Windows itself (on a Mac you have a get info command and then have the option to set the default open width also)
Well good to know I am not blind.
Odd that wmv does not show up in preferences/file type associations. Usually when it is not listed it is not supported, but it works fine.
I find it amusing that after 55 people have looked at this post only 1 person has looked in preferences/file type associations for .wmv. Or has any idea if it is not listed why it works?
