Today when I turned on my computer I noticed that two icons I had remove from the dock yesterday via dragging them off (cloud of smoke) were back. So I removed them from the dock again and did "killall Dock". They were back again (firefox and trillian). Well I uninstalled Trillian as well as repaired my disk permissions in the disk utility. That still didn't work. Firefox and trillian remain on the dock after restarting finder, killing dock, and even restarting the computer. No matter how many times I drag them off, they will reappear after some kind of restart. Trillian, however, is now a grey question mark because I uninstalled it. I also checked the permissions on my HD and Home folder. I was the owner of both with read & write access. I dont understand why this is happening. Can anybody help me out please? Sorry about the long paragraph.
