I noticed the following issues with IE8:
1) Sometimes when I middle-click on a link, it opens the new tab, but says it can't connect. If I then do a Refresh, the page loads properly.
2) Tabs would sometimes just "crash" out of the blue, after which the tab would re-open, and the popup balloon will show that they are being "recovered", or whatever. This even happens to tabs that are not the currently selected tab. Out of the blue.
3) Tabs would somethimes take 15 to 30 seconds to open. I have seen others complain about this too.
So when is IE9 to be expected, and is the focus really on speed this time (and hopefully also more standards-compliance as well as bug fixes)?
