Yesterday I had a pile of stuff fall on my keyboard while a program was open. Today, the program opens but I can't see it.

The program was open but invisible on the screen in Windows 7. The window shrunk to a size of zero and wouldn't even let me maximize to view! Re-installing didn't work. Right-clicking the preview window and selecting Maximize wasn't a option. Alt+Tab and WinKey+Tab didn't do the trick either (although WinKey+Tab looks pretty cool). Cascading or stacking the windows by right clicking the start menu bar didn't do jack!

I had to use WinKey+Up Arrow to maximize the window (after I clicked on the preview window on the start menu bar) and then drag the title bar down to un-maximize. At first I just clicked un-maxmize, but it dissapeared again. When it was back to normal, I closed and re-opened to make sure the size stuck. Sure enough, it did!
