Last night on my dell desktop I went to windows update via the startup menu and noted they had an update available for definition for ie8, a small file which I downloaded without issue in both my desktop and my dell studio laptop. Today, I found that when attempting to use tabs, the whole thing just froze up on both the desktop and laptop.
In the end, I had to uninstall the update, restart, then use system restore to go back which seems to have fixed the issue.
Has anyone else experienced anything similar? I'd say maybe it was a download issue but as I had the same experience on both platforms it seems to me it might be a MS issue.
