The Visual Thinking window obviously doesn't work right for me with my typical CM8000 installation, and I have no idea why. I'm familiar with it from CM6000, so I know how it's supposed to work. Presumably it is supposed to work the same in CM8000 as in CM6000. I'm running an OEM version of W98se, and Internet Explorer 5.5 (which includes some windows updates too) with all of the latest updates available online from Microsoft. If it were Windows 2000 or Windows ME, that might explain it because apparently they aren't supported, but supposedly CM8000 supports W98se. WP
