Did that too at first. Many reasons from video drivers to pests. For now it's still in Beta so we may want to wait.

Just remarking that IE 7 installation caused constant dr. watson problem when set to home page, and 3 desktop icons referring to forums, icluding this one, were changed and the drop-down menu just offered 'print' instead of 'open'. I uninstalled without a problem, just wondering if this is a common problem.
