I have a *lot* of keywords; I keep one for every person in any of my photos. When I use the search feature to search for keywords, the dark black window that appears to let me choose a keyword stretches up above the screen, making the first few dozen keywords impossible to search for, since the window does not scroll.

So far I’ve been able to overcome this by using the wide variety of Smart Albums I have, but that won’t work forever.
There’s a flight simulator hidden in Google Earth, and it’s a lot of fun. I just spent the better part of an hour flying from my place to my parents’ place to Sonja’s parents place and then attempting (unsuccessfully) to land at John Wayne Airport. I think I came in too fast (200mph seems a bit much).
Note that before I managed to do all that, I was crashing every few minutes, because I was using the keyboard controls. My flights consisted of moving in a straight line, then trying to turn, then getting into a tailspin and crashing. Over and over. But the mouse controls are nice; just hold the mouse button down near the center of the screen, and move the position to shift in the various directions, keeping in mind that it’s a joystick and you move the opposite direction that you want to go.
