Right, downloaded a pic (i believe its a screenshot of a movie, but i dont know!) off Limewire, and it refused to open (previewer said "No preview available") so i deleted it, but for some reason there was no "Delte" "move" or "Copy" in the context menu, pressing delete and nothing happens, drag and drop doesnt work either, what can i do?

Oh! i can see it under linux, but i cant delete it!

Are you up to date with SP2 and all security updates? Are you using FAT32 or NTFS? Can you right-click and select Properties?

A. Yes (last updaated a week ago, but will do it now), and im on XP Pro SP2, running on NFTS, and no, i cannot select prperties

open up a cmd.exe, terminate explorer.exe from task manager then use the cmd prompt to delete the file.
