Last night, Apple released a Windows update for MacBook machines running Boot Camp. It's not clear yet whether you can or should install this on all MacBook/MacBook Pro models, or just the newest (unibody) versions. If you've been running Windows on these new MacBooks, then you know how fickle the Multi-Touch trackpads are. This update will hopefully help matters, as we've received quite a few tips about trackpad problems in Windows (not to mention the numerous postings on the Apple discussion boards).
Apple tell us that the update "Improves the performance of the Apple Multi-Touch trackpad when running Microsoft Windows XP and Windows Vista on a Mac computer using Boot Camp."
You can download this update from the Apple Support Downloads website. It is a Windows executable, so you will need to be running Windows to install it. It is available for both Windows XP & Vista.
On a side note, the download page for the update shows an... interesting, and previously unknown version of Vista, at least to anyone browsing right now (it will probably be fixed shortly). We can only imagine that "Widows Vista" is coming soon to a computer near you.
Thanks to Ryan, and others who sent this in!
