I can't empty my trashon my 2011 MBP, running Lion. I've deleted a 'locked' image file and the trash won't empty it, even though it asks me if I want to just empty the 'unlocked' items or 'everything' I click 'empty everything', but it's still there afterwards. And I can't 'put it back' either to unlock it and then delete it. Restarting doesn't help either, trash still shows the item there. It's a small file, but trash showing crap in it is driving me bananas!!
