No problem. Explorer has only crashed once since yesterday (and out of the 3 enhancements, WindowFX was the culprit), but I'm pushing it pretty hard (constantly rotating the cube between desktops, using the TopDesk flip 3D over and over again, and minimizing, restoring, and moving windows around with all the WindowFX bells and whistles) so that's not bad. I'll see how long it takes to crash again. I definitely recommend this combination, though, if you want to make the visuals of your XP machine approach (and even surpass) what Vista can do out of the box.
