Yesterday, Microsoft pushed out a batch of new fixes for the Windows 8.1 Preview and the Windows RT 8.1 Preview. The five fixes, one classified as Important and the other four Recommended, are separate from the security fixes that arrived on Patch Tuesday last week.
The most welcome fix, judging from complaints Iíve heard, is KB2868208, which fixes a bug with Windows 8 apps that use scrolling ListView controls. The behavior is especially noticeable with the Windows 8 Twitter app (and with third-party Twitter apps), where scrolling is so jumpy as to render the apps almost unusable. After installation, scrolling is noticeably smoother.
