Any way to make OS X notice a change in screen size?

When you click the little green plus icon on an OS X window frame, the window expands to fill up the available screen real estate. Well, most of the time. It seems to me that OS X often doesn’t notice when the display changes. For example, I may launch a number of apps while using my big monitor at work and then when I go home, I’m using only the smaller PowerBook display. Now if I click the little green plus icon on these apps, they often expand way too much; enough to fill the previous screen dimensions. Quitting the app and relaunching works of course, but I don’t always want to do that, because I may lose some state like undo history, etc. Is there some other way to force OS X to adapt to the new display settings?

It occurs to me that perhaps I should create a Mac OS X annoyances page. The first two items would be this issue and the fact that you can only resize windows from the bottom right corner (which sometimes ends up off-screen). This post has a few of the annoyances that I might’ve listed and also mentions, in the long and interesting comments, some of the software that I’m already using to get around them – e.g.: Quicksilver and MenuCalendarClock.
