Droid X - is Blur home running when you use Launcher Pro?
Yes, that's an accurate observation.

I don't have a Motorola phone myself, but from what I understand Blur is embedded pretty tightly into the ROM.  Trying to remove it would be painful at best, and probably just cause your phone to start crashing.  I'd recommend flashing a custom ROM that either never had Blur (e.g. something built largely from the AOSP like CyanogenMOD) or a heavily customized version of your ROM that has had Blur thoroughly rooted out and replaced with stock apps.
