"You still have to grab the top to move, unless you use the keyboard"
Apparently I wasn't clear. You describe my experience in XP, but in Windows 7, I find myself moving the window when I wanted to stretch it instead. That is, I can move the window by grabbing it on either side and the bottom, not just the top. I view this as a bug, not a feature. It makes it hard to stretch the window. If I try and try again, I can get it to stretch. My question is, what subtle thing makes it move instead of stretch? Is no one else having this experience in Windows 7?
As for your suggestions about the double arrow problem, does no one else have this problem? I do what you suggest, wiggle the pointer until I finally get the behavior I want. I have tried various resolutions and Personalize/Display settings and the behavior is the same in all.
Again, I'd be interested to know if others have this problem. My mouse is a Logitech Trackball. But I've just now experimented and I have the same problem with the mouse pad on the laptop. It's a dell XPS L702X.
