Hi Bill,
ColorThink 2 has not been orphaned. We put out an updated (Mac) version for CT2 only a month ago. I'm sure the Windows version will be next. One of the big roadblocks here is that the software we use to compile a new version has not been updated for Windows 7 yet. So you're waiting for us, and we're waiting for them. It's always a good idea to wait a bit (if you can) before jumping onto a new operating system or update, if you really need the use of the programs. It always takes a while for the industry to get up to speed. Some companies, especially small ones like ours, will take longer than others.
