Ack! Seems an issue has cropped up.
IE8 Released
It's out there. Better hold off deploying it until you have tested all your browser-based apps and are sure that there are no incompatibilities. A few of our developers using dual screen machines found that after the IE8 install, the second screen was disabled and uninstalling IE8 fixed it.
The Wall Street Journal PC review honcho Walt Mossberg, who stated that browsers by now are the most important piece of software on a computer, thinks IE8 is a big improvement over IE7 and a "much closer competitor to its main rival Firefox." (which he still prefers over IE8 by the way)
IE8 looks to have improved stability, better compatibility with web standards, easier navigation and search, and better privacy and security. Redmond also leapfrogged competitive products with new features like Web Slices and Visual Search.
According to Redmond, IE8 is supposed to stop "two to four times more malware attacks than any other browser; cuts down on the time it takes to complete common tasks on the web such as searching, mapping and sharing, including navigating 15 of the 20 top worldwide sites."
Not an issue if you don't use dual monitors.
