A pretty weird install...it asks if you want to uninstall WB 5, and when you click yes it does but it asks you to reboot, but continues with the install of WB 6. If you don't reboot after you uninstalled WB 5, you will have problems.
Had the exact same thing happen to me, but after the initial hiccups, it seems to work great now
I'm loving all the new customize options.
And I gotta say that the start menu on Molten is absolutely amazing, it took me somewhat by surprise, and I freaked the cat out lol
