I have two 21" monitors at work which I attach to my early 2011 MBP (running 10.8.1) and I move various windows between the monitors. Sometimes the windows coming down to my laptop's screen are larger than it so they fit the maximum height (but are over the maximum width) of my built-in LCD.
I can resize the width of a window by clicking its left or right edge and dragging, but when I try to resize the height, and it shows the up-arrow (or even in the corner where it shows the diagonal arrow), I can click and drag as much as I want but it doesn't resize the height, it only moves the window left and right if I move my pointer either direction.
In other words, the height is stuck when the window is the height of the screen. This only happens when the bottom of the window is at the top of the dock. When windows are smaller than the screen, resizing is fine.
Is there any way to resize a full-height window on my LCD without moving it around then dragging from another corner or something?

Are you running any sort of third-party window management software? That's the only reason I can think of that this wouldn't work for you.
I can resize the height of my windows using the arrows on any visible edge, including the top and bottom of a max heigh window, and the diagonals. I tested this with the Dock hidden and visible, on the side and bottom, and with a window with a size exceeding that of the screen. Worked every time.
If you're not running any third-party software that might be interfering with window resizing for some reason, the only thing that comes to mind is that your mouse is very sensitive and you're moving it slightly before the click to resize actually registers.
You might also be interested in Moom. It's a pretty handy window manager that can do things like save preset window configurations for different display set ups, or do one-click window resizing to match a specific size in pixels (which you can bind to a hotkey). It's not a solution to not being able to manually resize, but if you're moving windows around different displays often, you may find it handy. Divvy is another popular app that does some of the same tasks, but I haven't tried it myself.
