Could be an app, sure, but useing the same apps (obviously), ADW runs fine, it hasn't FC'd on me once. And considering LP ran fine for a week straight when I had autorotate disabled, and then immediately started FC'ing again when I reenabled autorotation, that points to a problem with the launcher and not an app. If I leave an app that is in landscape and jump back to LP in portrait, it's a fairly good chance it's going to FC. And this is from several different apps, like Angry Birds, Homerun battle 3D and XScope. Just doesn't feel like an app issue to me.
