The default configuration for the VS.Net IDE is two combination windows docked to the right of the screen and tiled vertically(by which I mean one on top of the other). The upper window has the Solution Explorer, Properties Window and something else tabbed in it and the lower window has Dynamic Help and something else tabbed in it.

The other day I inadvertantly undocked the lower window (I am still getting used to the touchpad on my laptop). The upper window expanded to take all the available room in the right docking space. I fooled around for some time and couldn't figure out how to get the two docked windows to tile vertically again. They kept tiling horizontally (one next to each other) which results in two long skinny and unusable windows.

I was able to reset the whole thing to its original configuration, but I would like to be able to customize these window groupings in my own way.

How do you get two windows docked to the right (or left) side to tile vertically in the docking area?
