We've already brought forth a bunch of drivers and fixes for both AMD and NVIDIA cards during the past few weeks, but it so happens that AMD has another one to offer, albeit a really small one.
The newest downloadable package that AMD posted is not a driver per se, but an update, of sorts, to the Catalyst 11.9 driver.

The file is a standalone executable that works on Windows XP, Windows Vista and Windows 7, 64-bit or otherwise.

Four 11.9 WHQL driver versions are available for desktops (XP, XP 64-bit. Vista/7, Vista/7 64-bit), plus two for notebooks.
