In my case, when I get a .docx, I quite enjoy emailing back saying "we not not have the latest version of the Micro$oft software used to generate this document"
Isn't that double negative saying that you do have it?
The one major problem issue I had with Office 2007, is that Micro$oft, decided in their usual arrogant fashion that they would install a half gig MSOCache folder on the primary drive without the user/customer having any say. Tough on those folks who wish to keep their OS partition lean and mean..
I raised this point on my Partition Specific Thread. I'm still waiting to load my new W7 on a second machine, mostly because I don't want to use a third party's soft to reduce that Cdrive down to 100 gigs. Keef suggested bootiong in one of the Linux type OSs and I searched for my $1 disc that had been sitting on the shelf for ages. I'd just had one of those "must clear everything out" days. It was gone.
Every time I throw something away!!!!!
My good old Word Perfect generates a good MS Word .doc Strangely, it won't convert other .doc's to .wpd's
