Everytime I open Internet Explorer in Windows, it automatically changes my default for opening files on my mac; all my Excel and Word files anyways; haven't checked the rest. I tried the reset windows applications in 'Applications', but the next time I open Internet Explorer, it does the same thing. If I open a different program in Windows, my related files on my mac change their default to that one (open Excel Windows, mac excel files become defaulted to that). Is there a way to make all my mac programs the default always, and just choose the different programs I want to open sometimes?
