Great tips, thank you. Expanding the panel helps a bunch and the mouse wheel works well, too. I didn't have any luck with the CTRL +/- to expand and enlarge. Perhaps others should try it and confirm if it really is a bug. I'm sure Adobe would want to know if it supposed to be there but doesn't work.
With the expanded control panel taking up a lot of my main screen, I decided to move the main screen to my secondary monitor then put the 2nd image on the main screen, using the full screen for the photograph. This works well but it took a moment to figure out. There are no commands to do this, but it is simple. Just turn off the second screen in the 1 - 2 panels on the bottom left, drag the application to the second screen, then turn the second screen back on. The screens will now be in reversed position with the controls on what was the secondary screen and the full image on what was the primary screen.
Awesome product - I have a lot to learn. Jeff, when does Realworld Lightroom 4 come out?
