Printscreen doesn't work with Photoshop - Solution

Recently I've had a couple of incidents when pasting screenshots from printscreen into Photoshop didn't work — Alt Print Screen or Printscreen. Eventually, I couldn't even paste the screenshot into WordPad. This was strange, since I do this all the time, but only a reboot resolved it. Obviously, rebooting while you're working isn't too optimum.

Searching the Web, I found a thread at the Adobe forums in which a number of people complained of the same thing: Windows Clipboard won't paste in Photoshop CS3.

Well, I'm using Photoshop CS2, but at any rate, there's a link further down the thread to a page with the solution: How To Fix The Photoshop Clipboard (from the Microsoft News Channel at blognewschannel.com). And it takes about twenty seconds to fix.

I'm posting this here, since it took me a while to find it, and I'm not sure how many people will plow through the whole Adobe forums thread.

Added: the above link seems to error out now. Try this:
