A while back, I found that I could drag maximized windows in Windows 7 without first having to restore them. This is very handy for those of us with multiple monitors, since it saves a step. A few days ago, I discovered that this had stopped working. Unbeknownst to me at the time, this was a side effect of having turned off a feature that was annoying me—automatic window arrangement, formally known as Prevent windows from being automatically arranged when moved to the edge of the screen. When this feature is enabled, when you drag a window to the left or right side of the monitor, it automatically resizes to fit half of the screen.
For some reason, the ability to drag maximized windows without restoring them is tied to this feature. So, if you enable “Prevent…” (which I had done a few weeks ago), then dragging maximized windows no longer works. As with many computer options, these features are bundled into one—so you have to choose. For now, I’ve decided that I need to drag maximized windows more often than I am annoyed by automatic resizing. With three monitors—which together act as one single screen—I hit the left or right edge less often than I might otherwise, since the left and right “monitor” edges are five feet apart, and I tend to focus on the middle monitor for most work.
