Motorola Droid X

I just got my Droid X and downloaded a number of applications like the ones I had on my original Droid. I avoided the app killer application since that kept freezing my Droid, but I am seeing that the freeze is happening again and I have to remove the battery and reboot to get the X going again. I was wondering if anyone has found apps that freeze their Droid X and had to be removed. Perhaps we downloaded the same ones.
