Even with a 3 ghz machine, when you open a folder full of 36MB TIFF files, it makes life a bit rough when you're trying to work and Windows is gagging all over the stupid filmstrip thing.
Resetting each folder's default view to LIST only lasts until you log off, too. Then it's back to FILMSTRIP again. I know you can set folders for CLASSIC, but I really don't want to do that option as it eliminates the small previews and such.
