Over the last few days I've noticed a problem with missing icons. It seems to mainly effect icons in the Trash but I have one or two missing icons for videos and apps within the Finder and on the Desktop. The icon is completely gone - I have to click on the filename to select it. Quicklook works OK (for video). I can't think of anything I've installed that would have done it except Onyx, but I haven't run that in weeks. I did repair permissions a few days ago but I doubt that could break this. It persists after a reboot. I can't get it to happen on command, it just randomly occurs. Creating a New Folder always works OK. Anyone have any ideas?
