Here's, again, the webpage I'm working with, and I just tried to shoot a screenshot of:

And here's the screenshot, a result of a command-shift-4:
I'm using 10.6.1, but I think I've been seeing this for awhile now, even in 10.5. I don't get why this is such a mess. Shouldn't it be taking a direct screenshot of the pixels on my screen? That is how it used to work anyway.
Thanks.
This is really a Mac question, not an Adobe photoshop question so you'd probably get faster and better help over at Apple's website, but...
You're using Command-Shift-4. That gives you a target with which to drag around an area on screen and just capture that area. if you want the whole screen, use Command-Shift-3.
