Hi, Recently I upgraded to Snow Leopard, noticed some real improvements, etc. However, it has become apparent over the last week or so, that I am unable to delete any application from any folder on my system. I have tried changing ownership and permission settings to no avail. I have also tried using those application removal tools (AppZapper, AppDelete, et al). None of the files I wish to delete are 'locked' and I do not believe they are owned by root. I am not an expert in using the Terminal application, so I have not tried changing settings using this. I had intended to take my computer into my local Apple store, however, I wanted to see if I could find a solution online and fix it myself. I should also mention that I am not trying to delete pre-installed software, just third-party software that I no longer use. The best way of describing what happens after I trash an app is that almost immediately after trashing, the app seems to 'jump' back to its former place. Any help would be appreciated, Thanks.
