Hi, a very strange problem suddenly started to occur on my mid-2009 MBP. When I try to delete files (regardless of where the file is) it now prompts me to type my password to have the file deleted. When I do enter it, the file disappears from the computer, but no space frees up, and there is nothing in the trash can. What makes it even stranger is the fact that this is only a problem for my Admin account, the others have no problems with deleting files. Anyone? It's really frustrating!
