Okay I'm still a mac newbie. I have a late 2009 MBP and when I press my f12 key usually a thingy zoomed in over my screen that had like a calculator, world clock, weather, and something else. I liked this thingy. It worked this morning while I used it to help do some basic math (I'm not a math person). But a few minutes ago when I hit my f12 key it didn't pop up! Instead there was a little dashboard thingy at the bottom of my screen that slid in and said "widgets" and reminded me exactly of the annoying widget dashboard on my old PC. I don't know how or why it has changed. How do I get the cool "zoom in over my screen thingy" back?
