The thumbnails in Windows Vista are pretty nice. THey offer a convienent way to see what's in a window without having to open it. The only problem with these thumbnails is that they are too small, and there is no way to adjust the size. At least, there's not a way to natively adjust the size of the thumbnails. But this site (http://mpj.tomaatnet.nl/vista/) offers a program called "Thumbnail Sizer" which as the name suggests allow you to control the size of the thumbnails. No more tiny Vista thumbnails, this program allows you to make them as big as you'd like.
