How is print screen not working? Push the print screen key to capture the whole screen to the clipboard (hold down alt to just capture the active window), go into mspaint or something and paste it, crop and save the file, then put it on a web-server somewhere (one of the sites on
this list will be helpful). Then when you're making your post, click the 'Image' link and enter in the URL of your image. You can't actually post an image to these boards, you put the file somewhere else and then link to it.

P.S. google 'free screen capture tool' if you really can't get print screen to work, for some odd reason.
