When I depress the center of my mouse to access the calcualtor...
Huh? There's the Calculator app in /Applications and a calculator widget. With the widget it's hard to see the dimmed and enlarged windows anyhow. With the app, you should be able to se eal you currently open windows (unless somehow you enabled single application mode).
Now, some weird lego-type wall paper appears as the background. I see my widgets, but not the docs currently open. Duh!!!
Almost sounds like you enabled Exposé (press F9).
Here you mention widgets. So are you trying to use the calcualter widget or the calculator app. As I said widgets don't allow you to see the desktop except as a dimmed background and that is the way it has laways been, Tiger included.
