Hi Stefano,
How delightful to read your post! Welcome to the ColorThink forum and feel free to ask your questions. Your English is actually very good, and your comments as you say may help other Europeans with the same issue.
Your list of troubles sounds somewhat familiar to me. It reads like the list of issues we have fixed with our beta versions over time. So if you have just started using ColorThink Pro, my guess is that you are still on the original 3.0 version. Since the original release we have fixed bugs, improved speed and stability, and made upgrades for new operating systems - and rolled these into betas of our next version. So if you are not using the latest beta version of CTP (Version 3.0.1 beta22), we highly recommend that everyone do so. Even for people who are hesitant to try a software that is listed as “beta” - this really is a faster and more stable product than the original, and that’s why we make it publicly available. It is downloadable here:
