Beware of Internet Explorer 8 Beta 2. I have encountered a few major issues since I installed the latest beta. The last straw was when it messed up the most important utility on my computer, McAfee Security Center. This morning I noticed that my McAfee software was staring back at me blankly.
It took me half a day to find the source of the problem. Fortunately the solution is available on McAfee’s support forum. Easy answer: Remove IE8 Beta 2.
So it looks like the Beta 2 is off limits for the time being, until Microsoft gets their act together.
