Trash won't empty > Yosemite 10.10
I just downloaded Yosemite. The update sent several files including an iPhone.....restore.IPSW into the Trash. The other file I've been unable to empty is an IMovie. No error warnings -- it just sits and tries to empty for long periods of time. Stalls in the middle of each. I've moved each out of the Trash but it neither empties with the two or with just one. I've tried the Option Key hold-down, but that didn't work either. Thanks for any advice.
MacBook, Yosemite 10.10
