If you are using MS Office 2007, try entering =850*77.1 in a cell and see what happens. Now work that out on your calculator. If you support OOXML (the new, default, broken office 2007 format), you deserve all the pain that comes your way.

One more amazing screw up by Microsoft. Early adopters of MS Office 2007 (and Vista) must be feeling like real suckers… Microsoft’s second worst OS to date have received such negative feedback that they have finally given in to consumer pressure to simplify downgrading to XP. But ya, what do you expect? I mean, it was just a couple of days ago that the vice president of Trustworthy Computing at Microsoft, Charney suggested that security in Microsoft products has moved on from being the ‘laughing stock’ of the IT industry to something more respectable.
Unfortunately, it is the abundance of silly bugs like these that still earns Microsoft the title of ‘laughing stock’ in the technological community…
