Help with Desktop X objects

Hi all: I downloaded and installed two objects that I can't seem to delete. One is a spring clock (White Clock/Net Meter), the other a little cat (Necko Black). Both objects follow my cursor. My question is, how do I delete them? I have no problem deleting other objects by just right clicking and hitting delete object, but I don't get the delete object ability when right clicking on these two little buggers. They just don't want to go away. I've even totally deleted them out of Desktop X objects. Still they keep hanging on. I've unloaded and reloaded DX....still with me. I've rebooted my computer....still here. I'm getting very frustrated. Please, someone, help!!
