Why I can't I see my file names when using Mission Control?

It's not uncommon for me to have multiple Word Documents open at once and it's extremely annoying that they are no longer labeled like they used to be when I used "Hot Corners" in Snow Leopard. I missed out entirely on Lion but just bought an iPhone and figured I might as well upgrade to Moutain Lion on my computer while I was at it. Anyone else hate this particular feature of Mountain Lion or know how to solve it? I have already unchecked "Group Windows by Application" so at least they're no longer in a stack (thanks, Support Community!), but I still want to be able to differentiate between them at a glance. Any help is appreciated! I'm a longtime Mac user and not used to being so frustrated with my devices.
