I used CS7 and then 8 and just upgraded to 9. I LOVE Camtasia and their products & their support is great. But as a geek I have to say I don't believe 9 is ready for "production". There are so many issues that impact my productivity. Features have been removed that are needed (length of video for instance - which I already reported but many others), then "bugs" such as the interface responding inconsistently (menus delay in displaying or don't work when clicked), audio track disappears after an edit and save - requiring me to exit and re-enter. I could go on. I have played with the idea of using Snagit to capture a video of the issues but I'm too busy with getting my project out, I can't serve as QA for Camtasia at this time. I do like how Camtasia does not blow up as often (memory leakage) which is why I converted almost all my current projects to 9 but am really struggling to get the project done. Please caution others who are in the middle / end of a project not to upgrade yet.
